Expectation Management
Other reviews mention that the rooms are small; it's hard to get an appreciation for just how small they are until you see them. The bedroom was about 6' x 8', or just slightly larger than a double bed. As long as that is what you're expecting, then you'll be prepared to enjoy your stay.
The service was good, if not overly helpful. The room was clean and appeared to have been recently renovated. There was a small LCD TV mounted on the wall (as there was no other place to put it!). The bathroom was clean and the shower water pressure was surprisingly strong for the third floor. 
The location is outstanding, with short walks to some good eating, the subway, and both Riverside and Central Parks. 
I would stay there again.
