We didn't meet Marianne, but her friend Severine who helped us check in and out was nice and easy to communicate with and was especially nice about the fact that our flight was delayed and we didn't get to the apartment until close to midnight. The apartment is quirky, charming, and artistic, and the location in the Marais is great. It is easy to get to the subway or to walk around the city and there are many little restaurants and shops nearby as well as the Sunday Bastille market that is a short walk. We had a very nice stay - thank you!
