About This Home

As of July 2026

Near the vibrant Cotati Downtown Plaza, this charming 2-bedroom, 1.5-bath townhouse-style condo offers the perfect blend of convenience and peaceful natural surroundings. Nestled in a serene, private setting surrounded by mature oak and redwood trees, the home backs to open space and features a fenced backyard complete with a garden and storage shed for added privacy and tranquility. Inside, the home has been thoughtfully updated with laminate flooring, dual-pane windows, granite kitchen countertops, an electric stove, and a new water heater. A high-end washer and dryer are conveniently located in the upstairs laundry closet near the primary bedroom. Residents of this small community enjoy two assigned parking spaces, one covered and one uncovered, plus ample guest parking. Access to a newly renovated solar-heated community pool. Ideally located close to weekly community events, the farmers market, coffee shops, and local restaurants, the home is also near Oliver's Market, Sonoma State University, and SMART Train access, placing you in the heart of everything Sonoma County has to offer, both indoors and out.
