Popular with business travelers, tour groups, and vacationers, the Radisson is an attractive hotel in a less-than-attractive neighborhood. Though not very scenic, the Theater District is convenient to both the Back Bay and downtown, and this would be a prime property anywhere. The guest rooms are among the largest in the city, and each has a private balcony with great views from the higher floors. Each has a king or two queen beds and enough room to hold a sitting area. The best units are the executive-level rooms on the top five floors of the 24-story building. The Stuart Street Playhouse (tel. 617/426-4499), a small theater in the hotel, often stages one-person shows. The hotel also has a seasonal golf school and practice facility (tel. 617/457-2699).
