The flat is fine (exactly as described), and the host is super hospitable: he always answered any questions and asked If we needed any help. We had no problems when arrived because he has a safe key box system.
The flat is really very close to the metro station and the supermarket. There is also a pharmacy and a few bars and restaurants (even McDonalds).
So if you are looking for a place to stay a few nights in Paris (as we were) - that’s ideal. Not expensive, close to metro and very comfortable :)
