NIce quirky hotel
Spent three nights here recently during a visit to San Francisco. We arrived over an hour before official check in which wasn't a problem as we were accommodated immediately. Taylor on reception was fantastic, asked why were in San Fran and pointed out loads of things to do and where to go. 
The hotel, due to the use of the building before it was a hotel, is a little quirky. The bare brick walls and room doors which open outwards add to the ambience. Wifi is free is you join the hotels frequent stay programme. This isn't hard to do and I signed up for this within minutes to benefit from this. The hotel has a hosted wine hour from 5pm to 6pm each night where you can sample one or two or more glasses of wine! This is the only hotel chain I know that does this.
The Blue Mermaid restaurant is good for both breakfast and dinner and worth a visit. Their clam chowder, although not sampled by me, has won awards and I'm assured is worth a try by my partner.
The location couldn't be any better as you are right next door to the cable car stop and right on the waterfront in Fisherman's Wharf.
