I can say that I had a wonderful holiday in Paris also thanks to Xavier. He really is a kind and helpful host and a great person to meet. There really is nothing to say about him, just that it was a pleasure to meet him!
Talking about the house, it is exactly how you see it from the pictures. It is perfect for people who are going to stay out all day, but if you stay home, you just have everything you need. Finally, the neighbourhood is one of the things I liked the most during my trip. The area where the house is is just magical; you will enjoy it at daytime and even walking around at night.
