The Morgans Hotel is outstanding and has an extremely pleasant rooftop cafe, and the rooms themselves are unexpectedly swank. The Wythe Hotel is a hotspot of Williamsburg, and has an amazing rooftop bar. The Ace Hotel is relentlessly hip and right in the middle of tons of stuff to do; plus it hosts Stumptown Coffee, an oyster bar, and an Opening Ceremony shop so if you’re into hemorrhaging money in diverse ways, it would be a good choice.
