Sacramento is too far for the "goals" of your trip. While the hotel isn't quite where you want to be, and while I wouldn't want to stay in that location for a week, it still should suit your needs pretty well. Its not that far up to Santa Rosa (where you can then take Hwy12 and do the Sonoma wine thing), and also Napa Valley isn't terribly far away. Further, there are lots of things going on in Marin Co., and you can also get to SF (for daytime activities) by taking the Larkspur Ferry if you don't want to deal with a car in the City.
