Excellent location, excellent hotel. It's older but charming. I stayed here for a work trip by myself and felt safe. The breakfast was just ok, but good enough to get your day started. I was able to leave my luggage for a few hours on check out day so I could explore the city before my flight. I had an issue with the TV (which is also older, probably the only thing I didn't like about the room) but they fixed it right away. I would definitely stay here again. The location is steps away from everything - Union Square, cable cars, Nintendo store.

The location is perfect so close to all the transportation and stores and coffee shops. Very clean room, staff were friendly and helpful. We stayed in a suite. The air condition worked great and the bedroom was located inside not facing street so was quiet. Free continental breakfast downstairs also was a nice service. We had a very comfortable stay.
