Two sets of French doors with screened sidelights invite in the breeze. The private guest suite includes its own entrance, living room, dining nook, kitchenette, queen bedroom, Carrara‑tile bath, washer/dryer, and a private patio with tranquil oak‑canopy views. Outdoors, decomposed‑granite paths connect shaded seating areas, an herb garden, and a lemon tree. Located in historic Boyes Hot Springs, walk to El Molino Central, markets, coffee, and the Fairmont Mission Inn & Spa. Minutes to Sonoma Plaza, Glen Ellen, Jack London Park, and wineries. New roof installed this year.
