As the former guest villa of Cambodian royal King Norodom Sihanouk, this serene, all-suite retreat was once an oasis for luminaries including Jacqueline Kennedy, Charles de Gaulle, and Peter O’Toole. Twelve of the 24 earthy suites—all done up in timber, stucco, and terrazzo—are set around a verdant, central courtyard, while the other half have private plunge pools. The retreat’s central house is a chic living room, regularly replenished with freshly baked cookies and a steady supply of wine and cheese. Its jasmine-scented spa, flanked by an intricatesandstone bas-relief, is equipped with four state-of-the-art rooms, each with a steam bath, shower, and private sound system. For an exclusive look at the nearby Khmer landmarks, Amansara will arrange for you to head out on a guided tour at dawn or dusk on one of its custom-fitted remorks (cycle-rickshaws).It’ll feel like you have the ancient sites almost to yourself.
