The place in terms of location was pretty good, close to bus stops and metro station. However the positives stop there, the sofa bed was extremely uncomfortable as it doesn't lay flat and dips quite considerably in the middle. We had to detach the mattress and lay it on the floor instead to be able to sleep.
We stayed there when Paris was consistently 30+ degrees Celsius everyday (for 3 days) but the place didn't even have a fan. The streets nearby are extremely noisy at night and the early morning. We unfortunately know this because we had to leave our windows open at night due to again lack of fan.
They don't have dedicated wifi. Instead, they ask you to login to the city wifi and give you a bunch of logins to try. At one point we had about 7 logins which all didn't work. Incredibly frustrating and annoying.
When we checked in at 2:30pm, they room had not been cleaned and when we returned at night though it had been cleaned had no toilet paper.
The shower basin is also quite dirty and mouldy.
