Excellent apartment. I stayed along with my wife and our 19-year old son, and the apartment fit us very well, very comfortably.
It's a very convenient place for it's located close to a train (RER) station, Champ de Mars/Eiffel Tower, groceries, cafés, bistros, etc., but in a less busy square.
Alexandre was a great host, always very friendly, responsive and accommodating.
