Right next to the Charles/MGH stop, the John Jeffries isn't only easily accessible, it's affordable—a veritable home run in this city. The turn-of-the-20th-century building, across from Massachusetts General Hospital, was once a housing facility for nurses. Now it's a four-story inn with a Federal-style double parlor that serves afternoon tea or coffee. Rooms are full of handsome upholstered pieces; nearly all have kitchenettes. Triple-glazed windows block noise from the busy Charles Circle, and many rooms have river views. Nearby Charles Street is home to lovely cafés, specialty stores, and antiques shops.
