I found my Manhattan accommodation through AirBnB. It was my first time using their service, and it certainly won't be the last.
I selected this place, and it worked out great.
Mike and his girlfriend Natalia were really nice hosts, and the accommodations were just as described.
I'm now thinking of abandoning the search for a full time roommate, and offering the master bedroom on AirBnB instead. Hmmm ....
