Mandarin Oriental, Boston

What the classifiers highlight

In Back Bay next to the Prudential Center, a private entrance lets guests reach the mall's shops without stepping outside through Boston's long winters. The lobby follows feng shui principles, its front door aligned with the Charles River, and the 16,000-square-foot spa runs a vitality pool and a Kinesis wall. Newly renovated in 2020, Forbes rates the hotel five stars.
