I've been at the Alain's apartment for 3 days with 3 frineds and we found the home perfect. Unfortunally we did not meet Alain but his uncle Simon welcomed us with joy and was ready for help us; he also admit us to leave our luggage in the apartment untill the last day afternoon.
In the apartment there was everything we needed including bath foam and shampoo.
The apartment was warm, despite the cold days we encountered, with comfortable bed and it was well clean.
The house is very pretty and well decorated, really near the metro station Chatelet - les Halles, just in front of the church of St. Eustace; from there you can reach the Louvre museum in 5 minute and l'ile de France with Notre Dame in less than 10 minute by walk. When I will come back in Paris I will surely search for the Alain's apartment.
