Wonderful trip to Paris, and I couldn't thank Viviana enough for allowing us to stay in her apartment. The area is quiet during the day, but lively at night, with lots of bistros, grocers, shops, and patisseries close by. The apartment is also very close to the metro stations (Etienne-Marcel, Les Halles and Chatelet - - Etienne Marcel was our "home" station), and an easy walk to the Pompidou, the Louvre, and the Seine.
Yes, this is a top floor apartment (6th floor), under the eaves of the roof. The French don't rely on escalators and elevators like Americans do, so be prepared. There is also no central air conditioning, which is the norm in France. We happened to be in Paris during their "heat wave," but the fans that were there provided plenty of air circulation and cooled the apartment well. There were several grocers nearby, where we could stock up on water and snacks and there is a laundry close by also.
If you want to stay in the Montorgueil area of Paris, and feel like a member of the community and a real Parisian, this is the apartment for you!
