Gilles' place is at a very good location, close to everything on foot or by metro. The host was friendly too. Things were fine except that it is on 5th floor and the lift was only accessible and available if the host is around, otherwise guests use the stairs. So make sure you can manage your bags up and down or pre-arrange strictly for the lift with the host. In our case, we were lucky on arrival that the lady was at home and reachable but when we left, it was early morning so we had to use the stairs. We had a good stay in Paris overall.
