We loved our stay in the roof-top flat! The windows opened to a great view, and brought in the breezes which made the flat comfortable for sleeping. The apartment was comfortable and homey (a bit tight around the table in the middle of the room, however). It even has a piano and plenty of music to play. The kitchen is spacious and well-equipped, although with the abundance of great restaurants and cafes in the area, we didn't actually take full advantage of the cooking opportunities. There are great boulangeries and fruit markets in the area as well. (Maison Landemaine was one of our favorites nearby for a really good pain au raisin.) Pere Lachiase cemetiere is within walking distance (Cafe Mirabelle is a great place for brunch on the way!) and La Bastille and Le Republique also within walking distance (as is Place des Vosges and the various markets). Getting around the city was easy with access to the Metro line 9 right outside the apartment.
Communication prior to and during our stay was excellent. Although our hosts were not on site, they made sure someone was able to check us into the flat. We highly recommend this home away from home if you are planning a trip to Paris!
