We had a wonderful experience staying in Pierre-Yves's apartment! We stayed with 6 adults and were comfortable with one adult on the sofa bed. The apartment was very clean and well prepared for our group. Pierre-Yves was great with communicating with our group prior to our trip and during our stay. If we had any questions, he was quick to respond. The apartment is located in a quiet neighborhood with the exception of the occasional ambulance (from the hospital near by--although we didn't really notice it after the first day) We did feel the need to be extra quiet inside since the apartment is old and the floors creek loudly. It is walking distance from multiple metro stations. Elevator access was helpful with heavy luggage. We would stay here again if we returned to Paris!
