Catherine is a perfect host and was very helpful throughout our stay in Paris. The apartment is exactly how it is advertised and was actually larger than I expected. The windows open on to Rue Mazarine which is a beautiful small street with many cafe's and art galleries. The street is lively at night without being loud, and the bedroom is on the opposite side of the apartment so it is completely quiet even with the windows open. The location is incredible and is in the heart of some of the best neighborhoods in Paris.
