very convenient location
In my travels to SF it has come to be common knowledge to me that this city has some very small rooms with high price tags and this hotel is no exception. So in all fairness that is my only comment to size as it would be unfair to single this hotel out as having very small rooms when it seems that most of SF does. 
You can not beat the location to the BART or the cable car stop on a major line and those are the best ways to easily get around the city. Both are literally right there outside the lobby. 
The hotel has some minor rough edges in need of attention in terms of minor maintenance needed but overall was a very nice experience due in large part to the very nice staff and terrific location to mass transit. We will be back 
I do wish they would change their room service though. It is closed completely for a hour mid morning - odd! and apparently did away with my favorite from them in SF, the sourdough french toast.
