True gem in the heart of San Francisco

Amazing place to stay. The staff was very friendly. We were able to check in a little early and even upgraded to a larger suite at no additional charge. Also they held our luggage while we waited and the day of check out before we left to the airport to return home. The stay included a great continental breakfast. The location is next to the Union Square next to many shops and restaurants. We will definitely stay there again when we visit San Francisco again. We highly recommend it and the price was perfect.

Beautiful hotel and a great centralized location. The room was always clean and the staff was out of this world. The only thing is, if you didn't get to the continental breakfast when it opened, you will likely not get anything as they do not restock the pastries or refill the coffee.
