Nice hotel for price

Beautiful charming hotel. Extremely clean. Great location. Only negatives would be the ridiculous $25 fee per day for nothing and the breakfast that has only sweet stuff, not even a piece of bacon or a boiled egg. Also, no gym

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!

The receptionist was super helpful and let me check in early. However, the hallway is very narrow and the room was smaller than what the pic showed. I guess it is normal for inns in the downtown area.

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.

Cozy spot in San Francisco

It close to Union Square, up from the Powell BART station. Its also close to all the major theaters. Next door is a high end Steak Place. the room was light airy and clean. Good hot water pressure in the shower. Pleasant staff in the lobby. We will come back
