Perfect location for a trip to San Francisco
I have stayed at this hotel many times since 2006 and it is now my favourite hotel when I travel to San Francisco. It has a perfect location on Market Street. The F-line tram has a stop just outside the hotel which takes you all the way to Fishermans Wharf and many other attractions in the city. 
The rooms are small but clean and cozy. It can be a little bit distrubing with noise from the street at night.
I stayed for 2 nights and had no problems at all. I would highly recomend this hotel if you plan a trip to San Francisco.
