Excellent hotel all around
Stayed here for 5 nights for a conference. I found the staff to be very friendly and accommodating. The room was very clean and unique. The bathroom was excellent, it looked as if it had just been renovated. It was very quite, could only hear a bit of noise from the street below but I wasn't on the Geary St. side. The room was a little small, but there was just enough room for a cot. Also, getting a goldfish in the room was awesome. Free coffee in the mornings is nice (none in the room but I find getting it from downstairs is easier anyway). The gym was large enough with lots of equipment, and the sauna and hot tub are great to relax in after (for free!). 
The location is excellent for tourists, close to the street cars, lots of restaurants, shopping, etc. About a 10-15 min walk to the Moscone center. Starbucks about 2 seconds away. A great sushi place called Ryoko about 1 min away. Overall, very central - you can get to most interesting parts of SF in a cab in less than 10 minutes.
Highly recommend.
