The apartment is as described, very charming and with high ceilings. It is in the 4th floor without elevator. You find the Metro and RER within 2 to 5 minutes walking distance and all the big shopping centres around the corner. The location of the apartment is really great. It is very quiet since the windows look in an inner court.
Although Sylvia could not be there she was always at hand via SMS and fast answering.
We definitely would stay in this apartment for our next visit.
