4 star hotel
Area: Financial District South
0.16 mi from Crocker Galleria
Best Rooms: The views offered from this hotel are limited to Union Square from even numbered rooms or Yerba Buena Gardens. However, because the building is surrounded by other buildings, you'll need to get on a high floor, above 20, to get a view.
Best Rooms: The hotel is only 7 stories tall, so you won't find much in the way of views. However, some of the King rooms facing Bush Street offer views of Chinatown.
Best Rooms: There isn't too much in the way of views, as the hotel is surrounded by buildings, but rooms facing Bush St. on floors 2 - 8 are your best bet for views of the city.

Area: Union Square
0.30 mi from Crocker Galleria
Best Rooms: Rooms facing Powell Street have great views of the Union Square Park from all floors.
Best Rooms: Rooms facing Howard St. offer views of the bay, better from floors 25 - 28. The north side of the hotel has limited views due to obstruction from the neighboring St. Regis Hotel. The Fabulous Corner Rooms, ending in *02 (e.g. 2002, 2102), have great views of the bay out of one window and AT&T Ballpark from the other.
Best Rooms: Rooms facing Powell Street offer excellent views of the famous cable cars. Other than views of the cable car, the hotel doesn't offer much in the way of views, as it's only 6 stories high.
Best Rooms: Luxury Suites, Studio Suites and the Executive Rooms are all available with views of the Bay. For a Studio Suite with a view of the Bay, request a room ending in *06 (e.g. 1506 or 2106). These rooms are very large and offer great views.
