The Spa at Mandarin Oriental

Tucked deep within the hotel, the Spa at Mandarin Oriental is truly an urban retreat — not a peep of the noise from Boylston disturbs the tranquility. The dressing room, equipped with a whirlpool and crystal steam room (plus plush Frette robes, fresh fruit, and cucumber-infused water),is an experience in itself. But the services are what set the Mandarin apart: Many of the massages, facials, and body treatments are Eastern-inspired, though New England–sourced herbs are often incorporated.
