The apartment is nice and in a perfect location, in the middle of Marais. It's small for a family of 4 people, I think it would be perfect for 2. Very well equipped and clean.
Unfortunately we had a very bad surprise at our arrival: in the hottest days of the year, the AC was not working and we weren't advised. The host put a cooling machine but it was really not enough in those hot days. Certainly it was bad luck...
