Christian's place is exactly as advertised in the listing and was very clean. It was fine for our family of 2 adults and 2 teens. There is one toilet room with sink and a separate shower room with sink, so that makes it a little easier for 4 people to get ready in the morning. The location is a short walk from the RER station, so unless you have tons of luggage there is no need for a taxi or car from the airport. The immediate surrounding area is somewhat touristy (being so close to Notre Dame), so there are lots of souvenir shops and tourist restaurants in the area. Not saying that as a negative, just how it is. The area is quite lively at night, but you hear none of it inside the apartment. There are also a couple bakery & pastry shops a few minutes away (and a Starbucks...it is quite difficult to find iced coffee in Paris). Christian himself was fabulous, he allowed us a slightly early check in and was there waiting for us when we arrived. He also arranged for us to leave our bags while we walked around on our last day, since we had a late train departure, and saved us from using the station's luggage lockers. Overall, 5 stars for being as advertised, clean, central location and accommodating host.
