Stayed there for 5 nights with wife in a studio suite.
Rooms: Very nicely done, spacious by NY standards, with all the amenities. Decor is modern (somewhat of a Zen concept). The only two nitpicks here would be that the lighting is dim, even with all the lights on, and views aren't that great.
Service: Top notch, gracious, friendly, and knowledgeable. They really go out of the way to make sure your stay is comfortable. I've been writing reviews on this site for a long time and don't usually spend much time talking about the service (wife and I generally prefer to be left alone), but here it's worth a mention.
F&B: Good bar, but not very private since there seem to be many non-guests. Breakfast was decent, didn't have chance to try dinner.
Location: Hotel is on 37th and Fifth, a few blocks from Korea Town, and quite honestly not the best-looking part of town. I used to live in NY for 15 yrs so I know my way around the city, and this location is not going to be to everyone's liking. It's somewhat centrally located (not that far from wherever you're going), but then again it's really not walkable from anything (other than K-Town and perhaps Times Square if you're in the mood for a long walk). I was at this hotel for a function and I liked this hotel a lot, but for us location wasn't ideal since we like to eat and hang out in SoHo and West Village. If your interests take you more uptown, similar concerns. I think this hotel's location is best suited for people who are relatively new to NYC, whose itinerary takes them all over the place. Otherwise, our personal preference is to stay downtown near our interests, or go for something upscale near Central Park
Overall, this is a solid choice for a trip to NYC.
