Built on trust,made for Erasmus.

In a time when international students are often taken advantage of by greedy landlords, platforms, and scammers, Co-Erasmus helps the community swap rooms in a safer, more personal way. You can explore possible swaps, ask questions, and build trust first, while private details are only shared once both sides are ready to commit.

Verified listing⌄

Verified before going live

Before a room appears on Co-Erasmus, the user creates a profile, lists their room, and submits institutional proof such as a student ID, enrollment certificate, exchange confirmation, or university-related document.

One possible active swap⌄

One committed swap at a time

Students can message different people before deciding. Once both sides commit, each person can only have one active swap during their exchange period. This helps avoid double-booking and last-minute confusion.

Private until committed⌄

Private until both commit

Exact room addresses and contact details are not shown publicly. Before commitment, students only see the general area. Private details are shared only after both students mutually commit to the swap.

Mutual commitment⌄

Mutual commitment agreement

After both students commit, Co-Erasmus generates a downloadable agreement with the key swap details: room information, exchange dates, contact details, and the conditions both sides agreed on.

Details
Hey Jonas! I checked with my landlord, and we can go with the swap. It would just be a normal subletting contract.

That's great news :)
The only thing is the date mismatch. I'd arrive on Sept 1, but you leave on Sept 5. Do you think that could still work?
10:26✓✓
Yes, I think so. You can drop your luggage at my place, and I can ask a friend if you could stay on their sofa for those few days.
10:28
That would help a lot, honestly.
Then should we commit and unlock the details?

Sounds like a plan!!

Still have questions?

  • Is Co-Erasmus free?
    Yes. Co-Erasmus is free for you to use.
  • Does Co-Erasmus verify student status?
    Yes. Before your listing goes live, Co-Erasmus verifies that you are connected to an Erasmus-related exchange or institution. You will be asked to upload an institution-related document, such as an enrollment certificate, exchange confirmation, or similar proof.
  • Do both people need to agree before committing to a swap?
    Yes. A swap is only committed to when you and the other person both clearly agree to it. Until then, nothing is final.
  • Can I use Co-Erasmus if I am only looking for a room and not offering one?
    At the moment, Co-Erasmus is built for people who are both leaving a room behind and looking for housing during their exchange semester.
  • Can I talk to the other person before committing to a swap?
    Yes. You can chat in-app before committing. We encourage you to ask practical questions, talk openly, and make sure both sides feel comfortable before moving forward.
  • Will I know who I am swapping with?
    Yes. Before committing, you can review the other person’s profile and room information. Private details, such as the exact address and contact information, are only shared after both sides commit. We also encourage you to have a video call before finalizing anything.
  • Can I cancel a swap after confirming?
    Cancellations should be avoided whenever possible because they can seriously affect the other person’s housing plans. Co-Erasmus is designed to reduce this risk through clear communication, mutual confirmation, and structured commitments.
  • Does Co-Erasmus handle contracts, rent payments, or deposits?
    No. Co-Erasmus helps you find and coordinate possible swaps. Final contracts, rent payments, deposits, and landlord permissions remain your responsibility and should be handled directly between you, the other person, and any relevant housing provider.
  • What happens after a swap is confirmed?
    Once you and the other person both confirm the swap, Co-Erasmus creates a written mutual agreement summarizing the intended swap. This helps both sides stay aligned on the room, dates, and basic expectations. After confirmation, you are both considered committed for that semester, which helps reduce overlapping commitments on the platform.
  • Will my exact address be public?
    No. Your exact room address is not shown publicly. Before a mutual commitment, other users only see general room information, such as the city, area, photos, rent, availability, and room details.
  • Do I need permission from my landlord or housing provider?
    In many cases, yes. Co-Erasmus helps you find and coordinate possible swaps, but it does not replace landlord permission, rental contracts, or local housing rules. You are responsible for checking what is allowed in your own housing situation.
  • Can I swap if my dates are not exactly the same?
    Yes. Erasmus dates are often not perfectly aligned, so you can talk with the other person and decide whether a small date difference works for both sides. A swap should only move forward if you both clearly understand and accept the dates.
