About this home

Unparalleled serenity surrounds this Marinwood electrified home on Unionstone. Your first steps inside lead to a large great room w/ a direct view to the back patio & mature garden. Three bedrooms line the hallway that wraps around one side of the great room. The premiere bedroom & en suite bath are on the opposite end of the home providing the perfect place for rest. This spacious layout leads to a dining space, breakfast nook & updated kitchen. Relax during winter storms & summer heatwaves when using the recently installed heat pump. It provides heat and air conditioning, all supported by the solar panel system. Just push the button & you can make your electric window shades move, insulating your home from heat & sun. Solar tubes invite rays of sunshine to fill the rooms w/ natural light. Hardwood floors, pristinely painted walls, epoxy finish in the garage & updated LED light fixtures all reflect the careful maintenance of this treasure. When you are ready to play outside you can take a dip in your hot tub, relax under the pergola, or run around on your lush front lawn. You will love being surrounded by mountain views, hiking & bike paths. A simple commute w/ easy freeway access & a central Marin location. A nearby popular community center offers pools, creek & lively events.

Wonderful 4 bedroom/2 bath home with fantastic location on one of Marinwood's best streets. Roomy open floor plan with gleaming hardwood floors, freshly painted interior, updated kitchen and ensuite bathroom, and dual paned windows. Lovely backyard and peaceful setting with plenty of sunshine, beautiful views of the surrounding hills and hot tub. Easy access to spectacular hiking and mountain bike trails and award-winning schools (Mary Silveira Elementary is less than 2 blocks away). You'll also enjoy the Marinwood Community Center's terrific park, playground, tennis courts, swimming pool, summer camps, holiday parties and summer concerts. What a spectacular place to call home.
