One of the most common messages we receive at StayXchange goes something like this: "I just got my acceptance letter — I don't know anyone in Buenos Aires yet. Can you help me find roommates?"
The answer is yes — and it is one of the things we do best.
This guide explains exactly how roommate matching works for exchange students and international interns coming to Buenos Aires, based on our direct experience connecting students from universities including Torcuato Di Tella University (UTDT), ITBA, UBA, UADE, and Universidad de San Andrés. Whether you are arriving for a semester or a short-term internship, this is the process that gets you from "I know nobody" to "I already have roommates and a confirmed apartment" — often before you even book your flights.
Why Roommate Matching Matters More Than Most Students Realize
Finding roommates is not just a cost-saving exercise. For exchange students arriving in Buenos Aires without an existing social network, your roommates are often the first friends you make in the city. They are the people you explore neighborhoods with, cook with, go out with, and build your Buenos Aires experience around.
Getting matched well — with people who share your budget, your lifestyle, your schedule, and your general approach to living — sets the social tone for your entire semester. Getting matched poorly, or not getting matched at all and ending up in an apartment alone, is one of the most common reasons students tell us their first weeks in Buenos Aires felt harder than expected.
At StayXchange, we treat roommate matching as seriously as apartment matching. The two go together — and when both are right, everything else tends to follow.
Who This Service Is For
Our roommate matching is designed primarily for international exchange students coming to Buenos Aires for a semester, typically 4 to 5 months, through universities such as UTDT, ITBA, UBA, UADE, and Universidad de San Andrés.
We also work with international interns arriving for short-term internships of 3 to 6 months in Buenos Aires. Their housing needs, budget ranges, neighborhood preferences, and lifestyle priorities are generally identical to those of exchange students, so the process and the service are exactly the same. One thing international interns should be aware of: since exchange students make up the majority of our community, there is a good chance your matched roommates will be exchange students rather than fellow interns. In practice this has never been a problem — the profiles align very closely.
If you are arriving alone — whether as an exchange student or an international intern — roommate matching is the fastest and most reliable way to secure both an apartment and a social foundation before you land.
How the Roommate Matching Process Works — Step by Step
Step 1 — Browse the Listings and Express Your Interest
The process starts on the StayXchange listings page, where all available apartments are presented with full details — number of bedrooms, neighborhood, price, amenities, and photos. You browse at your own pace and mark the apartments that interest you.
The number of bedrooms tells you the size of the group you will be matched into. A three-bedroom apartment means a group of three. A two-bedroom apartment means a group of two. This is almost always how it works — one private bedroom per person.
Step 2 — Fill Out the StayXchange Matching Form
Once you have a sense of what you are looking for, fill out our matching form. You can find it directly on the StayXchange homepage — look for the line that says "Coming alone? Join the Roommate Matching List" — and we also send it privately to students who reach out to us directly before finding it.
The form covers:
Your personal details and contact information
Your semester or internship dates
Your budget range
Your neighborhood preferences
Your lifestyle and living habits
The specific apartments you are interested in
This form is the foundation of the entire matching process. It takes around 5 minutes to complete. The more honest and specific you are, the better we can match you with compatible roommates and the right apartment.
Step 3 — We Match You With Compatible Roommates
This is where StayXchange does the work.
We review your form alongside the forms of other incoming exchange students and interns who have expressed interest in the same apartments or who share compatible preferences. We match based on:
Arrival date and semester duration
Budget compatibility
Neighborhood preference
Lifestyle and living habits
Apartment interest overlap
When a compatible group is ready — three students for a three-bedroom apartment, two for a two-bedroom — we bring the group together. You are not randomly assigned to anyone. Every match is based on genuine compatibility across multiple dimensions.
Step 4 — Meet Your Potential Roommates
Once we have similar interests and preferences, we create the group and introduce you to eachother.
In the group you can:
Introduce yourselves and get to know each other
Ask questions about the apartment and the neighborhood
Communicate directly and quickly with StayXchange
Decide together whether you want to move forward as a group
Have a call with the group and with StayXchange staff included
One thing students consistently tell us they appreciate: we respond fast. Every inquiry, whether on WhatsApp, email, or through the contact form — receives a response within hours. Our maximum response time is 24 hours, even during peak periods.
Step 5 — No Commitment Until You Are Ready
This is one of the most important things to understand about how StayXchange works: you are not committed to anything until you explicitly confirm.
After being introduced to your potential roommates and the apartment, you can take the time you need to decide. You can ask more questions, look at the apartment details again, get a feel for the group, and then make your decision without pressure.
If you are happy with the apartment and the group — you confirm and we move forward. If something does not feel right — the apartment, the group, or both — you can step back without any obligation. We will work to find you a better match.
This flexibility is one of the things students tell us they appreciate most about the process. You are making a decision about where you will live for an entire semester — you should feel completely comfortable before committing.
Step 6 — Group Confirmation and Contract
Once the group confirms, we coordinate with the landlord, administrator, or property representative to move forward.
An important clarification: the rental contract is solely between the property's responsible party and the students — each student signs individually as a tenant. StayXchange is not a party to the contract and does not provide legal advice or legal assurance of any kind.
What we do provide is guidance. Based on our experience reviewing many rental contracts in Buenos Aires, we review the contract alongside you, share key points to pay attention to, flag anything that looks unusual, and answer your questions as best we can. Our goal is that you arrive at the signing stage informed and confident — not navigating an unfamiliar document alone in a foreign rental market.
To secure the apartment, the group may be asked to pay a reservation fee to the property representative — this amount is deducted in full from the first month's rent, so it is not an additional cost. Upon arrival, students complete the first month's rent and pay the security deposit as established in the contract.
For full details on terms and conditions, read our Terms and Conditions.
Once your group is confirmed and your contract is signed, the remaining steps — reservation fee, arrival payment, deposit, and monthly rent — follow a clear and structured process. Because the full booking process works the same way for all exchange students regardless of university or apartment, we have put together a complete dedicated guide covering every step from first inquiry to arrival.

When You Arrive in Buenos Aires
Once you land, your housing is already confirmed and your roommates already know who you are. StayXchange provides personal accompaniment throughout the arrival process — if questions or issues arise with the apartment or the property representative, we are reachable directly and respond within hours. Our goal is that your first day in Buenos Aires is spent experiencing the city, not sorting out housing logistics.
How Long Does the Matching Process Take?
There is no fixed timeline — it depends almost entirely on when you contact us relative to the peak inquiry period for your semester.
Here is how it works in practice:
During peak periods — the fastest matching: Hosting universities in Buenos Aires typically send formal acceptance letters in April/May for the July/August semester, and in November/December for the February/March semester. When acceptance letters go out, we receive dozens of inquiries simultaneously. During these peak windows the matching process moves very fast — students who contact us during peak periods can be connected to a compatible group, introduced to potential roommates, and have a confirmed apartment within one to three days.
Before the peak — slightly longer: If you contact us before acceptance letters have been widely sent, we will let you know that the process may take a little longer. Most other students will not yet be actively searching, so there are fewer profiles to match against. We keep your form on file and match you as soon as compatible profiles come in.
After the peak — act fast: If you contact us in June or July for a July/August semester start, the best apartments may already be gone. We always recommend contacting us as early as possible — ideally the moment you receive your acceptance letter or confirm your internship dates.
The honest advice: the students who get the best apartments and the best roommate matches are almost always the ones who contact us earliest. During peak periods the process is fast and the options are abundant. Waiting costs you both speed and quality.
What Makes a Good Roommate Match
Beyond logistics, compatibility comes down to a few things we pay close attention to when reviewing forms:
Schedule alignment — Are you an early riser or a night owl? Do you have classes every morning or a flexible schedule? Students with very different daily rhythms can find shared living difficult over a full semester.
Social style — Some students want a social apartment where people gather regularly. Others prefer a quieter home base. Neither is wrong — but mismatched expectations cause friction.
Budget compatibility — When students share an apartment, everyone needs to be comfortable with the price point. We only match students within compatible budget ranges.
Lifestyle habits — Cleanliness, noise levels, guests, and general living habits all come up in the form and we factor them into every match.
The goal is not to find you a perfect best friend before you arrive. It is to find you someone you can comfortably share a space with — and let the rest develop naturally once you are both in Buenos Aires.
Roommate Matching With StayXchange vs. Finding Roommates on Your Own
Many exchange students try to find roommates independently. This can work, but it comes with real differences worth understanding:
StayXchange Matching | Finding Roommates on Your Own | |
Apartment quality | We work directly with property representatives and review listings carefully before sharing them | No review process — quality varies significantly |
Compatibility matching | Based on budget, lifestyle, dates, and preferences | Random — based on who replies first |
Response time | Within hours, maximum 24 hours | Unpredictable |
No-commitment flexibility | Confirm only when ready — no pressure | Social pressure once connected |
Contract guidance | We review the contract and share key points — though legal responsibility lies solely with the signing parties | Navigate alone in a foreign rental market |
Coordination | Structured group from day one | Ad hoc and unstructured |
Local expertise | On-the-ground Buenos Aires knowledge built over multiple semesters | None |
Frequently Asked Questions: Roommate Matching for Exchange Students in Buenos Aires
What information do I need to fill out the StayXchange matching form?
The form asks for your personal details, semester or internship dates, budget range, neighborhood preferences, lifestyle habits, and the apartments you are interested in from our listings. It takes around 5 minutes to complete. The more specific and honest you are in your answers, the better we can match you with compatible roommates and the right apartment.
Do I need to have a specific apartment in mind before filling out the form?
No. Some students come to us with specific apartments already in mind from browsing the listings. Others fill out the form without any particular apartment — just their preferences, budget, and dates — and trust us to match them. Both approaches work equally well.
What if I don't like the group I am matched with?
There is no obligation at the matching stage. If the group does not feel right — for any reason — you can step back and we will work to find you a better match. We want you to feel genuinely comfortable before you commit to anything.
Can I be matched with students from different universities?
Yes — and it happens frequently. Exchange students from UTDT, ITBA, UBA, UADE, and Universidad de San Andrés often end up in the same apartment groups. In practice this is one of the best parts of the experience — you arrive already knowing people from different academic backgrounds and countries.
What if I am coming as an intern rather than an exchange student?
The process is identical. International interns coming to Buenos Aires for 3 to 6 months go through the same matching process, the same form, and the same introduction. The main thing to be aware of is that you will likely be matched with exchange students, since they make up the majority of our community — in practice the profiles and preferences align very closely.
How does StayXchange approach apartment quality?
We work directly with property representatives and review each listing carefully before sharing it with students — checking location, pricing, amenities, and the details of the property. That said, we always recommend students review listings thoroughly themselves and ask us any questions before confirming. As with any rental process, we encourage due diligence on all sides.
Is roommate matching free?
Yes — there are no separate fees for the roommate matching service itself. StayXchange's fees are related to the rental transaction, not the matching process. We will always be transparent about any costs before you commit to anything.
What is StayXchange's role in the rental contract?
The contract is solely between the property's responsible party and the students — StayXchange is not a party to the contract and does not provide legal advice. What we do is review the contract alongside you, share key points to pay attention to, and answer your questions based on our experience. Our goal is that you feel informed and confident before signing — not alone in an unfamiliar process.

Final Thoughts: You Do Not Have to Arrive Alone
Buenos Aires is one of the most social, vibrant, and welcoming cities in the world for exchange students. But arriving without knowing anyone — without a confirmed apartment, without roommates, without a base — makes those first days harder than they need to be.
Roommate matching through StayXchange changes that. You fill out a form, we do the work, you meet your potential roommates, and you confirm only when you are ready. Fast, flexible, and built specifically for international students navigating this from abroad.
Everything in this guide comes from StayXchange's direct experience connecting exchange students and international interns with compatible roommates and quality housing in Buenos Aires — semester after semester, university after university.
If you are ready to start, fill out our roommate matching form and we will be in touch within 24 hours — often sooner during peak periods.
