We stayed for one day at Adam's apartment in Williamsburg. The location is very good with a lot of bars and clubs in walking distance. A subway station is also close to his apartment, which brought us directly to Manhatten.
Adam is a very friendly and hospitable host. We asked him if we could check out later which wasn't a big deal at all for him.
If you are looking for a place to stay in New York City, I can highly recommend Adam and his apartment!
