Everything perfect! The apartment, the location, 50 meters to subway (Chatelet) 100 meters to railway (Chatelet - Les Halles) and mainly the host, Patrick gave us all the informations about the neighborhood, commerces like supermarket, drugstore, velib', how to mobilize in Paris, etc... The apartment has everything that you need, very practical, and everything there works.
Patrick is a great host. Thanks a lot. See you next year. :)
