Extremely well priced in a great area right in the heart of Union Sq/San Francisco and the room was very clean with the bedding & towels having that laundry fresh room smell. Yes, the room was quite small but perfectly manageable. If you want a bigger room in SF, be prepared to pay five times more. Staff all super friendly. And all the complaints about a free - yes FREE!! - breakfast in a 2 * hotel are baffling. What do you expect - vintage champagne, lobster and caviar? Besides, you really should be eating at one on San Francisco's countless superb eateries instead of filling up on dry muffins and cornflakes. Great hotel, 5 * all the way.

Best hotel breakfast...but the line was super long and crowded. First floor room had street sounds all night and they put us in a handicap room that we didn't need and the shower didn't work properly. The food is good and the bellman Abdur was an excellent person. He helped us make a really smooth exit and arranged beautiful transportation to cruise terminal pier 27
