The room was smaller than we expected, actually it was the smallest apartment we've ever seen but it was fully equiped.
We had a sofa bed, a super tiny bathroom, all kitchen's appliances. The location was good, in walking range to the Paris Gare du Nord, 5 minutes walk to the metro station.
Sandra gave us a very detailed instruction to get into the apartment and how to check out but we didn't really meet her . A small minus was that after our stay, Sandra kindly asked us to pay 20 Euros because she checked the room and saw the bed's frame was cracked (but we were sure that we didn't do anything rough).
After all, we don't feel very comfortable with the stay but still recommend to the young travelers if you don't mind the small space.
