Great big house in a good location with views of mount diablo. The house is a 7 minute drive to downtown walnut creek. Great attention to detail on the finish work throughout the house don't miss the crown molding and the built in speakers...
downstairs. Awesome pool in the backyard with 3 waterfalls flowing into it. Good size usable yard. The home has a very nice dining room with ambiance light that is very warm.
