No frills, but quiet at night and clean
No frills: no hotel robe, no hotel shampoo, and most annoying, no water glass in the room, not even a disposable one. What are you supposed to do when you brush your teeth? I had to get myself some plastic water glasses.
I am a woman who was traveling alone but I was not surprised at the transients near the hotel. That's what you get in downtown San Francisco, even with the hotels that are more upscale than this one. 
Positives: The place was quiet at night after the reno work ended for the day. The hotel was clean and the staff was friendly. I would consider staying here again, although I would check other options.
