The 79 suites (other units are standard doubles) are by far the most residential-feeling hotel accommodations in Boston. And on this part of tony Commonwealth Avenue—close to Newbury Street, Kenmore Square, and (across the river) MIT—the residences feel really comfortable. From the subtly patterned carpets, bed linens, and upholstery to the marble-clad bathrooms and French doors between rooms in the suites, it’s all exquisite. Courtly, personalized service only adds to the charm of the place.
