3 star hotel
Area: Prudential - St. Botolph
0.95 mi from Boston Opera House
Best Rooms: The side of the building facing Boylston St. offers decent city views. Rooms ending in *05 (i.e. 605, 705) sit at the corner of Blagden and Exeter Streets, and depending on how high of a floor you're on, you may be able to catch a glimpse of the Charles River; these will likely be the best views offered from the hotel.
4.5 star hotel
1.06 mi from Boston Opera House
Best Rooms: The Harbor Suites may be a bit steeper in price but are surrounded on three sides by views of the Boston Harbor. The Sara Josephina Hale Building has rooms with better views of the harbor, but keep in mind that the rooms in this building are reserved for those who book Fairmont Gold rooms.
Best Rooms: For the best river views, the Deluxe rooms (or the Executive Suites, if you don't mind spending a few extra dollars) are your best bet.
4 star hotel
Area: Seaport District
1.20 mi from Boston Opera House
Best Rooms: Views from this hotel are of the city or the water. For the best of both worlds, request a room with a combined city and water view, on floor 10 or higher. Some guest rooms are interior-facing, which means they face towards other rooms in the hotel.
