This hotel is well located, welcoming, clean and charming. If you want a big chain with lots of so-called amenities look elsewhere. If you want a comfortable, clean, quiet room, a warm welcome, a comfy bed at a reasonable price, this is your hotel. We live in the South Bay and come up to SF for theater, restaurants, and time with friends. This will be our go to from now on!

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.
