Fairmont

The Fairmont’s sunny, marble-floored lobby, so full of plants it looks like a greenhouse, instantly lifts the spirits. The pool, garden patio and 415 vast, bright rooms do the rest. The fitness center offers up-to-date machines, a lap pool, squash and racquetball courts, aerobics classes and massages. Everyone, staff and guests alike, seems happy to find themselves here. Pets are also welcome, and owners can get advice on pet-friendly places to take them in DC. The Fairmont Gold, a "hotel within a hotel," is a club floor with separate check-in, and free continental breakfast, afternoon tea and evening cocktails in the private lounge.
