About This Home

As of September 2025

Located just blocks from the Sonoma Plaza, this beautifully maintained 3-bedroom, 3-bathroom home is a hidden gem. Tucked behind a private gate and nestled towards the back of the property, the home feels like a private oasis, while being just steps away from world-class dining, wine tasting and more. Inside, light-filled living spaces create a warm and inviting atmosphere. The kitchen was fully renovated in 2020, and boasts custom cabinetry, Vdara countertops, stainless steel appliances, and an eat-in dining nook. The open living space has vaulted ceilings, a gas fireplace, and a wet bar elevating your entertaining potential. The primary suite is spacious and bright with a spa-like ensuite bathroom featuring a double vanity, and a large walk-in shower with beautiful Carrara tile. The outdoor spaces within this property are brimming with tasteful, mature landscaping, and enchanting entertaining areas. This exceptional property offers the best of wine country living, paired with the comfort and charm of a private retreat.
