Good service, but know what you're getting
We spent a week through a time share exchange. The hotel was very attractive, the service was very good. However, the Ballet room (which is the smallest) is pretty darn small. A bit difficult for two folks for an entire week, you have to just pile stuff in the corner or stuff it in the wardrobe. 
Our room was #27, would not recommend that one unless you like to be at the front of the property. The shades did not keep the light out from the front entry and there was street noise. There was also no central heat, used a portable unit to keep things warm. 
Breakfast was good, although the same everyday. 
There was a small frig, and microwave, good for any of the leftovers you might have, if you're trying to save a couple of bucks.
The neighborhood nearby has some good restaurants, like The Grove on Hayes Street and the Boxing Room. And, some great little boutiques.
The Inn is close enough to the BART if you don't mind walking, about eight blocks or so to the Civic Center stop. 
There are quite a few street folks, but no one bothered us the many times we walked back and forth to catch the train. 
Civic Center is one stop away from Powell Street shopping and Union Square.
Overall, the hotel was convenient, good, quick service and friendly folks at the desk.
