If you have ever lived in a shared apartment, when one of the residents leaves, it is also a pain to find someone!
With rents continuing to rise in France, shared accommodation has become a real alternative. The market has experienced explosive growth in recent years; listings now number in the thousands.
Based on these observations, four young people from Strasbourg created a website in 2013 to simplify life for roommates and landlords: The Roommate Map !
The Roommate Map: a simple and free tool
The principle remains true to the original idea: an interface based on Google Maps and Google Street View. You can immediately see the available apartments around a specific address. Green markers indicate vacant rooms; a click opens the detailed listing.
Access is completely free For prospective tenants. Landlords and current roommates post their listings free of charge, building a rich and highly responsive database. Each listing is reviewed before publication to eliminate duplicates and fraudulent offers: you save time and avoid unpleasant surprises.
Filters to target exactly what you want
Just below the search bar, the site offers a series of drop-down menus that can be combined with each other:
- All types : traditional flat-sharing, subletting, coliving, room in a private home…
- All rents : choose a specific range or leave the unlimited option.
- All available : immediate entry, in one month, on a specific date.
- All spaces : private room, independent studio, shared space.
- Amenities : Internet, washing machine, dishwasher, parking, balcony, garden, etc.
- All occupants : mixed, girls, boys, couples accepted or not.
- All accommodations : apartment, house, residence, coliving.

- More filters : advanced options (accessibility, pets allowed, smoking/non-smoking…).
