For me and my teenage daughter Marie's apartment was absolutely great. It was an excellent choice on perfect location close to La Fayette in safe neighborhood. 2 minutes walking from several metro lines and one grocery store with all we needed. Some restaurants are also on the street in front of the building. Appartment is very nice - nicely decorated, bright and very clean, and has everything one needs for a short or long stay.
Matress on the double bed seems new and we slept great. We didn't like the stairs to the 6th floor (seems usual for Paris), but after walking kilometres daily, we managed also the stairs and on the top, where we had very nice sunny mornings when we opened curtains. Even we were in Paris in the hottest period in June 2019, the appartment was not hot. I would not hesitate to recommend and hope to come back next time I am in Paris.
