Best Rooms: There isn't too much in the way of views, as the hotel is surrounded by buildings, but rooms facing Clay St. on floors 4 - 11 are your best bet for views of the city.
Best Rooms: Most rooms have views of the city; rooms facing California St. have obstructed views from floor 8 and below, while rooms facing Mason St. have good views of the city from floors 5 and up. Rooms on the northeast side, on the higher floors, offer views of the bay.
4 star hotel
Area: Financial District
0.37 mi from city center
Best Rooms: For the best view of the bay, as well as of Coit Tower and the Bay Bridge, be sure to book a Bay View room. Ask for one that has a balcony, so you can really experience the views. These rooms exist even on the highest floor, alongside the uber-expensive suites, so they're quite a steal.
Best Rooms: Rooms facing Mason St. that end in *09, *10, *12 and *14, from floors 9 - 12 (e.g. 910, 1112), offer nice city views.
Best Rooms: Cornell Hotel is encircled by equally tall buildings, blocking any potential views of the city.
Best Rooms: Though you won't find any sweeping views of the city, as the hotel is only 10 stories, the best city views are found from rooms overlooking Bush St., on floors 8 - 10.
4 star hotel
Area: Downtown San Francisco
0.24 mi from city center
Best Rooms: Rooms facing north face the bay, while rooms facing south look toward downtown. For a view of the bay, however, you'll want to book a Bay View room specifically, and request to be above floor 21.
