One of the best hotels in Boston faces the harbor and the Rose Kennedy Greenway, but the fantastic location is just one reason to stay here: Others include the superb service, a great pool and spa, excellent restaurants, and plush, luxurious rooms. The hotel even has an outdoor skating rink, under the landmark arch at the heart of the Rowes Wharf complex. In the guest rooms, mahogany furniture creates a residential feel; blue decor predominates, echoing the harbor, which is visible from most guest rooms. If you plan to be away from the hotel a lot, save a few bucks and book a city-view unit. There’s no such thing as a small room: All are at least 500 square feet. Accommodations start on the eighth floor of the 16-story structure, part of a red-brick hotel-residential-office complex that opened in 1987.
