Liked:It was safe, quiet and central. I was sick during my stay, and I spent a lot of time sleeping. The bedding was very comfortable! I also appreciated that it was walking distance to lots of restaurants and transportation. It was also nice that the hotel offers a continental breakfast.
Disliked:The hotel is in an old building so it appears a bit run down at first. But once I adjusted my expectation, it was totally fine. I can appreciate the charm of it. (I only mention this in case anyone is expecting something modern). As I mentioned before, it was well-kept, clean and comfortable. And very central to what I needed from my stay. I would stay here again.

Hidden gem

Liked:This hotel is a hidden gem. Literally hidden as I walked past it twice before figuring out what google map was saying. The entrance is tiny, with a tiny reception but the service was warm and friendly. My room is on the 5th floor, serviced by a small older elevator. My room however was nicely updated and very clean! Wha a nice surprise. And the ceiling fan was perfect to keep the air moving and at a perfect temperature. A continental breakfast is included, which is appreciated. Selection isn’t huge but perfectly adequate. And the location is perfectly walkable to streetcar, hop on hop off, major shopping and Trader Joes. Lots of cafes and options around. Price is more than fair for a San Francisco boutique hotel. Would definitely recommend!
