Concierge.com's insider take:
Right next to Capitol Hill, this Kimpton property was the first hotel to bring cutting-edge design to a very traditional, Federalist city. The first clue is the gleaming chrome and glass facade. (The second is the fact that Christina Aguilera has slept here.) Inside, the lobby is white coralina stone with lipstick-red sofas, and a black baby-grand piano sits by the reception desk. Each of the 139 rooms has custom furniture (a granite-topped desk, for example), black-and-white marble in the bathroom, bold mirrors, and a yoga kit (mat, block, strap) to use while watching the in-house yoga channel on the room's flat-screen TV. It's no accident that big pop-art dollar bills, by Warhol colleague Steve Kaufman, hang on the walls—the unconventional images of George Washington are a cheeky nod to the presidential history that is all around in D.C. Bistro Bis, a modern French restaurant, has a lively bar and a regular clientele of senators and congressmen.
