Mandarin Oriental Washington DC Rating: 4.5 Pearls
No other D.C. hotel comes close to rivaling the Mandarin's ultra-tony, top-notch spa, fitness center, and 50-foot-long indoor heated pool. The spa boasts eight treatment rooms for its full-service, Asian-influenced menu of massages, body treatments, facials, and nail care. The eponymous hotel brand products are all-natural and paraben-free. But treatments are costly.
Four Seasons Washington D.C. Rating: 5.0 Pearls
The Four Seasons' tri-level spa and fitness center, replete with a two-lane saltwater pool, is simply phenomenal. The full-service spa has eight treatment rooms and uses top-notch products from Kate Sommerville and Naturopathica, among other brands in the Who's Who of the pampering world.
The Jefferson, Washington DC Rating: 5.0 Pearls
The Jefferson only has three treatment rooms, but its small size doesn't make it any less luxurious. Highlights on the menu include specialized "vinotherapies" to reflect Thomas Jefferson's love of wine.

A grande dame hotel that's hosted presidents and diplomats since 1901, The Willard is home to one of two of Elizabeth Arden's Red Door Spas in D.C. It offers everything from makeup to body treatments, all in a soothing, grown-up atmosphere.
