We really enjoyed our long stay at Dominique's space. It was exactly as in the photos, modern bathroom, and very clean space. The windows let in great light, and room to cook in the kitchen, and a French press for making coffee. It is in a tourist dense area so there are always people about. There are endless places to eat, good food and wine shops with walking distance, nearby open air markets several days a week, and it is conveniently close to two metro stops. It is not a through traffic area, so traffic noise is light. It is walking distance from RER B station which we took in from the airport, and Dominique gave us exact directions how to get to his place. Once we figured out how to use the French washer even that went smoothly! It is also only up two flights of stairs, as some places are up more levels. Accommodations were very comfortable, though we did use the fans as it was still quite warm. Nice TV, but we didn't really use it as only found French stations, and ours is not good enough to follow. Internet worked fine.
Only downside is that location is in a busy area, above restaurants and local bar scenes, so it was noisy with windows open. However the bedroom is in the back, so with windows closed (and connecting door closed) there was no problem sleeping. If you are a light sleeper perhaps bring earplugs. I brought them but didn't need them. I would highly recommend this Air B&B to anyone staying in Paris.
