Part of the design-oriented Morgan Hotel Group, which also owns the Mondrian brand, the 876-room Hudson Hotel strives to be hip and fun as well as affordable. Its common areas -- lobby, restaurants, and lounges -- are spacious and high-design, offering room to party, relax, hold a meeting, and socialize. The stylish rooms, however, are tiny, accessed by barrack-like hallways and lacking amenities such as minibars and coffeemakers. But most guests are more interested in spending time at the dining and nightlife hot spots on site than staying in. More cultural pursuits from Jazz at Lincoln Center to Carnegie Hall and the Metropolitan Opera are all within walking distance.
