We had a wonderful time in Paris this weekend staying in Sylvia's flat. It is very centrally located. We enjoyed walks through Pigalle and Montmartre which are quite charming from the location. The apartment is clean and very comfortable - especially the bed, wow! We felt immediately at home. It is a 4th floor walk up (that's the 5th floor to Americans). So if you have trouble with stairs be aware there is no elevator. I found the added daily exercise to be a plus.
Sylvia was always available to respond. Very kind and attentive. She asked if we wanted the kitchen stalked with breakfast items before we arrived. I would stay here again!
