Guillaume is one of the friendliest and most helpful hosts I've encountered. He really goes out of his way to make your stay pleasant- he let me store my bags all day when I arrived so that I didn't have to lug them around Paris and he took his time to show me how everything in the flat worked when I checked in. In addition, the flat is spacious, clean, well-equipped and has a beautiful view. The neighborhood is trendy, has plenty of shops, restuarants, entertainment, and is a short walk to two metro stops. I would highly recommend staying here if you are visiting Paris.
