Christelle is a great host. We didn't get to meet her personally, but she replied to all of our questions quickly. We came in pretty late, but getting the key to the apartment was no problem. The apartment itself was clean and and there were plenty of instructions for guests. There was no noise from the neighbors at night and the neighborhood was also very quiet and clean. There are several metro lines close to the apartment so moving around Paris was easy. The apartment is on 4th floor and there is no elevator, but that was no problem for us. Overall we had a great time and no complaints!
