We were a group of 7 and stayed here for 3 nights. We mostly enjoyed the location of the apartment, close to the Louvre, Notre-Dame and Centre Pompidou, as well as many metro stations. Also, lots of restaurants in the area to choose from, as well as many boulangeries to grab something for breakfast.
However, we noticed that we windows were quite dirty, there were some holes in the furniture and paint was falling off the wall in a place. The soundproofing is quite non-existent, you can hear everyone in the building.
