There's that dang echo again. And confirmed with my sister where her friend lives - and the road leading up the hill from Sutter Creek has a number of signs for B & B places - so just google away to find one of those if it fits your preferences. :)

Here is one highly rated B & B in Sutter Creek http://www.foxesinn.com/

And there are others: http://suttercreek.org/stay

Near Plymouth is Deaver Vineyards. They also have an inn called the Amador Harvest Inn and own the Amador Flower Farm. All very close and nice place to base.
