I stayed at Phillipe's house with 6 of my friends on our Interrailing trip. Phillipe was very helpful with directions to his place and it's in a lovely part of Paris, a 1€60 metro ride away from the Eiffel Tower and all the touristy hotspots. Phillipe made us feel very welcome with 2 bottles of champagne on arrival and even some ice cream from Berthillon.
It's quite a small apartment considering there was 7 of us but it's very nice and homely, we fitted in the living room to sleep easily without being too crowded and all got a good nights sleep.
Overall everyone enjoyed their stay and would happily come again !
