Very average
I almost stay exclusively at Marriott properties. This was my least favorite. We never saw a bellman. The restaurant we were counting on was closed. Our first room we walked in wreaked of smoke. I know this isn't the hotel's fault. There are signs that clearly state "no smoking." And as usual, the staff was courteous and immediately provided us with a new room.
Also, the surrounding neighborhood is not the best, especially when thinking of the "UES." 
Also, the TV reception was horrible for four days. I understand one day as things happen, but four was ridiculous.
I usually stay in midtown and realized that staying so far North is a bit of a hassle.
