With too many amenities to list, the 148-room hotel has helped redefine luxury in town (pay attention, Ritz and Four Seasons) since opening in 2008, and it offers services many guests are calling "out of this world." Need your pants hemmed in 30 minutes? No problem. Feel like a pot of green tea at check-in? It's complimentary. Forgot your Gucci sunglasses? The store's next door. There is complementary house car service, too. The hotel's contemporary Asian decor does feel a tad out of place in Boston, but locals love visiting for a touch of the exotic. The limestone and marble lobby offers direct access to the Prudential Center and Copley Place, and other gallery-like public areas are adorned with art on loan from the Peabody Essex Museum. Large guest rooms—for the city, anyway—are outfitted with contemporary Asian design, soaking tubs, rain shower heads, and 400-thread-count Frette linens. Even if you don't drink, pop into M Bar for a look at the cool glass-topped, illuminated bar. And don't miss a visit to the quartz-crystal steam room at the outstanding spa, especially if you've overindulged on mandarin martinis.
