Christophe is a great host and will do his best to make your stay pleasant. His apartment is clean and spacious. His apartment is on an upper floor served by a creaky elevator. Also the nearest Metro station is a bit of a walk. We are good walkers and quite fit so this was not a problem and is quite typical in Paris.
The plumbing and electrical work. It was cool while we were there and so we did not use the AC. Also we did not do any cooking as there are many fine Cafes and Restaurants in the neighborhood as well as Delis for take-out. All in all a good place for your Paris visit.
