My fiance and I stayed at Edouard's apartment for 6 days and had the most beautiful time. The apartment is exactly like in the pictures if not better; filled with light and beautiful and charming details which, when combined with impressive collection of music Edouard has (that you can listen to in the whole apartment, even in bathroom as it was stated in previous comments) makes you feel as if you are in a movie.
The bed is very comfortable and suitable for 2 persons, kitchen is equipped with everything you could possibly need, bathroom as well and the whole place is very clean. Apartment itself is located on 7th floor (no elevator) so it may not be for everybody but it is worth the climb because the view from the apartment is breathtaking.
Edouard himself was the perfect host: communication with him was effortless, he welcomed us and even helped us with our luggage, made sure we were settled down and that everything was ok, even let us stay on the final day longer then previously envisaged. He showed us were the local markets were and offered his help if we need anything or had any questions, very nice guy!
The neighborhood as some comments stated is mostly African and we had no problems at all and felt safe at all times, even when coming back to apartment at 2AM. The whole neighborhood has very energetic vibe and we loved it. Metro station is 2minutes away and takes you to the center of city in 10 minutes and there are a lot of markets in the neighborhood and anything you could need.
Would definitely come back again, and we recommend it to anybody who is planning to spend some time in Paris- this apartment will add to your experience! :)
