My wife and our 2 small dogs stayed for an entire month at Gael's. The apartment is what you see in the pictures, well provided for a long stay like ours, with everything you might need (for example an iron). We were really confortable during our stay and it has a splendid view of the Eiffel Tower.
The accommodation is as shown in the pictures but it should be noted that the access to the apartment is through the service area, which means crossing the main building and its courtyard to enter a rather small elevator. Paris is famous for its small elevators, in this case we could only fit one big suitcase and one person at the same time.
The apartment is located in a posh neighborhood, walking distance of several metro access (line 1, line 2, line 6 and RER A) and few blocks away of at least 2 different supermarkets. The location, just in the middle of the Foch gardens, was great for the daily walks for our dogs.

If I had to point something out, it should be the communication with the host. Gael was very attentive and willing but our only way of communicating was through the app, no cellphone or contact number whatsoever, so many times this produced a delay between the questions and answers.
