A true ambassador to what the W brand really is, the W Hoboken is a jewel and often has rates that will save you some dough when in NYC. I highly recommend staying here if you're ok with taking a quick train under the river.
I don't know what I did to get so lucky... Wait, I do know! I used one of my handy-dandy Suite Night Awards and got upgraded to the --- wait for it -- Extreme WOW. So far, this has been the only time I've ever stayed in W's "best" room. Neither Extreme, nor WOW, even in combination, do this 17th floor paradise justice. Never before have I experience such refined luxury and exceptional, classy taste. Two huge bedrooms, two and a half baths, two balconies, sweeping views, sound system throughout the suite. WOW. Wow, y'all, WOW! Based on the style of this room, I'd guess all the rest is great, too.
The Living Room here is a step up from most Ws. The restaurant is great, room service is fast. Whatever/Whenever is reliable.
PATH train is about a 5-8 minute walk from the hotel. Takes you to a few places in Manhattan.
Fri and Sat night turn into a bit of a Jersey Shore in-real-life club night....but you can get away from that it you want.
