We thoroughly enjoyed our stay at The JW Marriott- Union Square. Great location the hotel is located in the heart of Union Square. Our room was very comfortable. All of the staff we came in contact with were friendly and helpful. Cynthia at the front desk was very pleasant and helpful. Room service is expensive as is the restaurant and bar. Unfortunately there are a lot of homeless people in the area.

Lovely every time

Just returned from yet another stay at the JW and recommend this property. Great location for everything. Rooms have nice glam decor, illy coffee maker, large room and large well appointed bathroom. Good views.
The mini suite was so nice we asked family to come to our room to have drinks vs going out. Helpful service. Spotless. Dark and quiet rooms made for great sleep. Well done JW!
Room service is pricey, to be expected. But my salad with salmon had a big chunk of wild salmon that was $14, a good value.
My only complaint is parking valet is $66! There is a garage across the street for half that.
