Tiny, Claustrophobic, Loud
If I'd taken my pillow into the elevator, I'd have spent a better night. 
The room was so tiny it felt claustrophobic. The wifi was erratic, but unfortunately the noise from the bar in the hotel center was not -- it was consistent and loud. The hotel itself is dark throughout, from the bizarrely unmarked entrance on the street, which leads to an escalator that leads into the lobby. I kept looking for another entrance, but that was it. It's dimly lit throughout, with the exception of the neon-green room doors that seem to glow in the hallways. (The new color scheme is, apparently, dark gray walls & carpet and neon green, and during current renovation there is no restaurant, no room service.)
I suggest looking elsewhere for your stay in New York. The Hudson is not at all worth the convenient location.
