We were a family of 4 on a brief visit to Paris and really enjoyed the apartement. Communication was easy, entry was hassle free, and the apratement was exactly as per its description. Location is fantastic, within walking distance to many major attractions and with an abundance of shops, cafes and restaurants around it.
The only negative experience was the faulty building elevator. It didn't work throughout our stay which meant we had to haul our luggage up and down to the 3rd floor apt. via the very narrow and winding staircase. No fault of Renaud's of course but still a point to take into consideration.
All in all a very positive experience, provided the lift works properly.
