4 free bedroom(s) in a shared 1 bedroom apartment in a 12m2 apartmentOkay, to create a listing, I would need the specific information for each category (House description, House amenities, House area, Room description, Room amenities, Transport, Address, House name, House area, Room area, Private unit type, Room name, Total number of tenants). However, since you did not provide me with these specific details, I will create a generic example based on the instructions you gave. You can replace the generic parts with the actual information when you have them.--Welcome to ;La Maison Partagée
