Decent hotel for the price. But...
Very old hotel but charming in its own way. 
We found it clean but on the small side.
The problem is the area. We witnessed first hand what looked like a drug deal going down in front of a sketchy liquor store. Had to pay for their locked parking. I feared for my rental car. Homeless people sleeping on the sidewalk. I would not even think about walking in the area.
We will most assuredly never stay there again. There have to be better bargains in SF.
