In a nod to the hotel's Asian heritage, this spa aims for zen-like ambiance and to be a place where guests may come to refresh their body, mind and spirit. Take a dip in their vitality pools, center yourself in a zen relaxation room or unwind in a steam area. Their treatment menu is designed to relax guests from their head to their toe. Try a time reversal facial to get rid of those pesky lines on your face or loosen up as staff massage your head and feet during their signature oriental harmony treatment. METRO: Smithsonian
