Good: This is as good a value as you'll get for downtown San Francisco. Literally blocks from union square and the area has tons of restaurants and clubs, not residential at all. Everything is walkable. The room was very clean. Hiromi was incredibly sweet and accommodating. Our flight was delayed and we came in around 5:30 AM no problem.
Bad: the shower could have been cleaner, which is shared among the floor( The bathroom, which is also change shared is pretty clean). The walls are a little thin, you can hear the bars playing their music.
Overall, what you pay is what you get. It's best for people who are gonna be out a lot so you don't pay insane prices in the area.
I would stay again and recommend this place.
