Concierge.com's insider take:

Hotel Max has secured the honor of hippest hotel in the city, located close to the Fifth Avenue shopping district. Decor is a crisp palette of grays, whites, reds, and oranges along with a selection of attractive hi-tech frills (flat-screen TVs, little CD players). There are also comforts you'd find in a more ostentatious hotel, such as showpiece beds piled high with marshmallow-soft pillows. The Max is all about promoting local artists, and each of the 163 rooms has original artwork, with each floor dedicated to the (often provocative) work of a different local photographer. There are some rock-star worthy amenities, too, such as 24-hour room service from the Asian-fusion/sushi restaurant off the lobby, and a "You Got It" button on each room phone, which you can use to challenge the concierge with bizarre 3 a.m. requests. Note that rooms are on the small side—but big enough to pass out in after a night of debauchery, which should give you an idea of some of the clientele.
