We stayed the last three nights of our three-week west coast voyage this autumn at the Hanlery Union Square. It really is almost on the square, where there was always something going on - concerts and street performances for example. All kinds of shops and restaurants are close by, and the cable car, metro, BART and bus stations in all directions are only a few paces away.
The hotel itself has friendly service, a newly renovated lobby, and is genrally very orderly. The restaurant next door (daily grill) has a great breakfast (not included in price, will come to 10-25$ per person), which we enjoyed. Our room was a bit small (it was one with a single queen bed) and had a window to an inner court, but that didn't really matter. It was sufficiently clean and had the amenities we needed. For the location, it was surprisingly quiet. All in all, I would say the hotel offered great value (we paid about 85 EUR/night) for the location.
