Dark, tiny, but relatively inexpensive
This is a great neighborhood (townhouse a few feet away is on the market for $6mm), a block from Central Park and subways, friendly staff, free (abeit weak) Internet. And if you don't book well in advance, you may not get a better price on a decent hotel in NYC. 
My family had a room that was bigger than most, and it was tiny, spacious enough to accommodate two beds and a dresser and that's about it. The bathroom is similarly scaled -- kind of like an airplane bathroom but a bit more cramped. I couldn't really see if the room was dirty because it was so dark, the only light coming from an air shaft, but it was definitely on the dingy side. Not enough outlets for all our gadgets (chargers for phones and computers). 
You could hear your neighbors using the bathroom and talking, and occasionally there were banging noises coming from the air shaft, like a piece of wood hitting something, that kept us awake at night. We also experienced all kinds of problems with the plumbing. (You would not want to share a room with anyone you didn't know real well!) No service elevator, so in the morning you have to suck in your gut and squeeze in tight with the maintenance/service staff and their carts -- we took the stairs, but that's probably not an option if you're on the top floor. 
Breakfast: ok. My son liked the waffle maker, but it was so gunked up that he could only peel off the pieces. The orange juice was good, but for coffee, you're better off hitting one of the neighborhood java purveyors. 
I thought I'd be okay staying in a place like this (having read the TA reviews) because it's New York, and you're never in your room, etc etc. And maybe for one night it would have been okay. But longer than that: depressing.
