J is very welcoming and explained us a lot of things about the city. We had a problem with the metro card, he came with us and help us, very nice.
Just few things : the room is not very well sooundproofed, the cleaning is not very good, and the street is not very secure, but the subway is at 300m. However, exept theses little things, we had a great stay in New York and thank you J for your hosting!
