Jean-Michel was a wonderful host, very friendly, answer very quicly and the check-in is flexible. The building has an elevator, but you need to climb a short flight of stairs to enter the apartment, and Jean-Michel helped with the luggage!
The flat is beautiful, cozy, very clean, has a lot of natural light and matches with the photos. And the view will amaze you, cause we can see the tradicional parisian roofs. You can walk everywhere and the surroundings have several restaurants and bars that are not expensive.
I'll definitely stay at Jean-Michel's flat again when I return to Paris :)
