Welcome to Villa Sorriso.
The property is 80 minutes from the Golden Gate Bridge.
Williams built the home himself in the early 2000s, according to The Wall Street Journal.
The library is all wood-paneled.
The kitchen has a huge range, and an island for extra cooking space.
The living room offers views of the surrounding Mayacamas Mountains.
The home has a 12-seat, state-of-the-art movie theater.
There's also a billiards room, in addition to two "safe rooms."
With 653 acres, there's room for amenities such as tennis courts.
And a 65-foot infinity-edge swimming pool.
There's a hot tub, too, for cool Napa nights.
The pool area has "his and hers steam showers and changing rooms, and a 'pool activities' room, according to The WSJ.
There's a small fishing pond on the property.
And acres upon acres of vineyards growing olives and grapes.
That landscaping is stunning.
$29.9 million buys privacy and serenity.
