The staff here were amazing! So friendly and helpful. Great location right at Union Square… close to many restaurants and lots of shopping options. Breakfast was minimal, but the room was quaint and well supplied. Would definitely stay here again.

Never again

Wouldn’t book here again, there’s was no built in AC, it was hot in the room. They only had a ceiling fan and a heater. Asked for a portable AC which thankfully they had. The guy who came and installed it didn’t even bother to hook it up to the window he assumed we were stupid and wouldn’t notice. The bathroom was very hot and the doors were like stuck you almost got to run into it to open the bathroom door. The room was extremely small and Front desk staff were rude at some point. No parking at all. What a disappointment, book away from downtown! Unless you want to struggle
Heater
The belt and shoe were there for a purpose the small vents wouldn’t point up towards the ceiling so we had to improvise
Ceiling fan that does nothing

The mattress was too soft and quite uncomfortable. The sheets were scratchy and the material too hot for comfort sleep. There’s no air conditioning so the room get quite stuffy but there was a nice ceiling fan. Also there’s only views of the walls of other buildings around so don’t expect an actual view of any kind.

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.
