We didn't see Christophe but he gave us detailed instructions, so we had no problems to get into the apartment. It's very easy to get there from CDG international airport. The apartment is very basic but had everything you need. The location is fantastic! Close to ask attractions (walking distance), good stores, restaurants and metro stations. It's very quite though is located in the very center of Paris. It's on the third floor without an enervator but it was not a problem for us. The bed is big and very convenient. There is also a sofa in the second room where a short person or a kid can sleep, but we didn't sleep there, so I can't say how good it is. Christophe answered all my questions right away. We enjoyed our stay in Paris and in Christophe's place. I would recommend the apartment to everyone.
