Walter Hinteler stayed there with a group of us during one visit, and Joe from Chicago stayed there with some of his friends as well.
Not posh but very nice. One block from the W Hotel at literally 1/3 or 1/4 of the cost.
I like that it is just a block from Union Square and the buses and subway system.
The street it's on (13th or 14th) has been renamed Lee Strasberg Way for the one block east of Union Square. His school is on that block.
Walking distance to the Strand Bookstore.
It's got location
