I had a really good experience at this location. Philippe was very quick to respond to any of my questions.
The one difficulty was in finding the location. One of the trains (RER C) was closed so it was a little bit more difficult to find the apartment, but the directions guided me there.
Upon arriving, Philippe's associate Cezar was waiting. He was kind enough to wait for me even though my flight was delayed about an hour and a half.
All in all, I found the apartment to have a fantastic location and to be very good for a traveler who wants to explore Paris.
