Mandarin Oriental, Boston
The $300 million tower of limestone, marble, and New England brick—designed according to feng shui principles, of course—offers massive Asia-opulent rooms and the largest hotel spa in town. Expect the perfect balance between contemporary elegance (touch-activated fireplaces; glowing marble and noble hardwoods) and sheer indulgence (cloudlike Ploh duvets; soundproof windows that actually open). To stand out in the fashion-forward Back Bay, designer Frank Nicholson approached the hotel as if it were a gallery. Everything has an artistic touch, from the blond-wood contemporary furniture to the masterpieces by Frank Stella and David Hockney. Frette, Gucci, and Elan Sassoon (son of Vidal) have boutiques within the complex, and diners can opt for the hotel’s Asian-flavored Asana restaurant or try L’Espalier—helmed by James Beard Award winner Frank McClelland.
