I stayed at the Best Western Plus Sutter House while in Sacramento for a conference and thought it was a great value. The hotel was very clean, free wifi always worked, and the staff was wonderful - so friendly and helpful. It was also a very convenient walk to the convention center and nearby restaurants. No need for a car at all if you're limiting yourself to the downtown area. My only recommendation would be to ask for a room away from the corner nearest the intersection if you're a light sleeper. I could hear some road traffic and the light rail at times. Didn't bother me but might bother someone who couldn't sleep if there was noise.
