If I could give it less stars.... I would!!!!!
Horrible horrible place to stay. We were scammed by Priceline who claims this dump to be a three star. They claimed they were fully booked after giving us two twin beds in a dumpy room. After complaining we got a queen bed. It was at least a queen bed but the room was still horrible! Ripped furniture and a musty odor. Didn't trust anything has been cleaned for ages. No ac. Window propped by a wooden stick. Heating didn't work. Bed was rock hard. Bed sheets were practically ripped. 
Overall miserable experience. Would never go back. The location is near japantown which was nice but I would have preferred something more central especially given the random weather in sf. 
Don't stay here!
