I spent a week at Edouard's apartment while attending a conference at Le Palais des Congrès (a short 5 minute walk away) with my partner. Edouard was away when we checked in to the apartment, but he arranged for us to pick up the keys at a restaurant next door which went very smoothly. Communicating with Edouard was very easy and he quickly answered any questions that we had, even though he was on vacation at the time! The apartment is Edouard's personal place of residence, so we were sure to be very respectful of the space.
We both found the apartment to be beautiful and comfortable, with excellent natural daylight provided by large windows on two sides and very comfortable couch/chair in the living room. The living/kitchen area had a large table to eat/work at and the bedroom had plenty of space for luggage. The living room can get pretty noisy but the bedroom in the back of the flat was quiet at night. Although we were in Paris during a heat wave, the cross breeze between the windows as well as the fan that Edouard provided kept us cool at night.
Just some things to note: the mattress is pretty hard and may be uncomfortable for some people. It is also on the fifth floor with no elevator so it was a great way to walk off all the croissants we had for breakfast :) Although there was enough for our arrival, we made a trip to the grocery store the next day to get some basic toiletries (toilet paper, soap and shampoo), which was somewhat similar to our next two airbnb experiences in France.
Overall, the apartment was in a wonderful location, very close to some excellent shops on Av. des Ternes (or some very expensive shops on the Champs Élysées) and some delicious restaurants (we enjoyed La Maison in particular). It is accessible via a couple of very close metro stops (Argentine and Charles de Gaulle - Etoile). We would happily stay there again!
