About this House

Tucked into a quiet hillside beneath a canopy of beautiful Redwoods, this 1,236 sq. ft. home has the kind of setting that's hard to come by private, peaceful, and completely immersed in nature, yet just steps from the Dipsea Trail, Old Mill Park, and the charm of downtown Mill Valley. Forty steps lead to the front door, where natural light pours through an array of windows and French doors that open onto both a front and back deck. The layout flows easily between indoors and out, with a warm living room anchored by a fireplace, a dining area, and an updated kitchen featuring a breakfast bar, pantry, and distinctive glass block windows. A guest half bath completes the main level. Hardwood and laminate flooring runs throughout, adding warmth and continuity. Upstairs, a floating staircase leads to two skylit bedrooms, including one with a private balcony overlooking the backyard, along with an updated full bath. A separate office with laundry provides the flexibility that today's lifestyle calls for. For those who love the outdoors, the location is exceptional with easy access to scenic hikes over the ridge to Stinson Beach and everything that makes Mill Valley so special.

    "The neighbors are friendly and the views are great. this neighborhood is positioned in the middle of the Dipsea, Cypress, and Old Pipeline Trails, so running, hiking, and biking is just out your front door. In the center of the neighborhood there's a large permanent designated Open Space Park Area that used to be the Old Mill Valley Reservoir that people, kids, and dogs walk and play in. Their are only 12 houses on the private road, so there's not a lot of traffic and it's quiet and peaceful. Once a year there's an annual neighborhood block party at the end of Edgewood Ave. "
