We loved our stay in Jean-Loup's apartment, the location is incredible. There are three metro stations close by, but the place is also so central that a lot of things, such as the Panthéon, Notre Dame or the Jardin de Luxembourg (and probably a lot of other things in forgetting now) as well as lots of bars and restaurants are in walking distance. The rustic apartment is in a very cute, historic house and staying there made is feel like locals. Since it is facing away from the street there isn't much noise coming from there, but being an old building the walls are thin and your can hear the other people in the house. Communicating with Jean-Loup was pleasant, quick and efficient. For us it was the perfect place to stay and we would return in a heartbeat.
Thank you, Jean-Loup
