Having stayed in a number of Airbnbs in Paris, this was overall a great place to stay in.
Location: Perfectly situated close to a lively social scene, great restaurants and shops. Easy to walk to many of the known sites of Paris and locales. It is close to several metro stations which I used heavily while in Paris. It is a bit noisy on Friday and Saturday so if noise bothers you bring some ear plugs but otherwise was quiet.
Checkin: Easy and seamless. We asked for 2 sets of keys because we were 2 families and were accommodated as such.
Apartment: Nice views of the Eiffel Tower to the west and north views as well. Bright, vibrant, and clean accommodation. Was able to accommodate x2 families and a child. Beds are comfortable and each room has ample storage space. The bathroom is better than most with space to move around. The kitchen is adequate with a washing machine in that area. I don't believe it has a dryer function as we couldn't figure it out but there is a drying rack in the living room if needed. The living room is nice and there is TV access to Netflix etc. The sofa has some stains but what would one expect after such heavy use as a rental. Of note this is an old French building and the walls are thin. The apartment building is mainly airbnb rentals as far as I can see but some tenants do live there and are polite.
Overall would stay here again in the future if available. Sylvain was always available and very communicative. Was a pleasure to be hosted at this apartment.
