I'm taking a trip to New York this fall and have been perusing online for hotels just in case the apartment we were planning on falls through. A friend of mine stayed at The Jane Hotel a few years ago and loved it. I think it's incredibly charming with all of the rooms mimicing a ship's cabin. The single and bunk bed rooms are about 50 sq ft each. They also have Captain's Cabins that are about 250 sq ft each and have a full/queen or king sized bed with a private bathroom.
