Average hotel
Honestly, I'm not sure that I would stay here again. I did win this hotel through a Priceline bid and so there really isn't too much that I can complain about. However, if I had paid full price for this hotel you can bet the tone of this review would be different. For the 4 nights that we were at the hotel we don't remember a single time when the hotel felt quiet or peaceful. We somewhat anticipated the bustle of the hotel simply because it is downtown in Union Square but we did not anticipate on several occasions there being a 5 minute wait just to use the elevators to get up to our room. It was crowded... and then some. We were on the 16th floor and actually had little issue with noise apart from the occasional loud voice in the hall. We had little encounters with anyone who worked at the hotel (apart from check in and check out). The rooms are tiny and the bathroom is microscopic. The bed was so so... but the curtains would black out the room in case you wanted to sleep in (which we did). 
Tip: When you arrive at the front with your baggage you can walk to the left and curve around to the elevators to avoid having to carry all your baggage up the very large set of stairs when you first walk in. We did not know this and carried our heavy bags up all those stairs... which was not fun. Don't expect much help with your bags unless you ask for it. 
Overall, I would not recommend this hotel for a normal visit, but would recommend it for a good Priceline bid.
