Tucked at the end of one of Calistoga's most coveted streets and bordered by the oak-shaded banks of the Napa River, 1316 South Oak is a private retreat where architectural charm and a genuinely park-like setting come together on over one-half sub-dividable acre. Three-bedroom suites, four full baths, and 3,066 square feet of beautifully updated living space offer the rare combination of town convenience and countryside seclusion moments from downtown Calistoga's tasting rooms, restaurants, and spas. A dramatic two-story foyer with travertine floors, a hand-forged wrought-iron Juliet balcony, and a sweeping, newly carpeted curved staircase sets the tone. The great room is crowned by vaulted ceilings with exposed timber trusses and a wall of windows framing the gardens; new wide-plank blonde oak floors and fresh paint extend throughout. The chef's kitchen opens to casual dining beneath a coffered, exposed-beam ceiling. The kitchen features a large central island with gas cooktop and stainless vent hood, double wall ovens, premium stainless appliances, wine refrigeration, and a walk-in pantry, all wrapped in soft, weathered-wood custom cabinetry. An octagonal turret-style sitting room, wrapped in arched Palladian windows, makes an inspired reading room or home office. A private bedroom suite on the main level offers ideal guest or multi-generational quarters; upstairs, two additional en-suite bedrooms with private river-view balconies are accessible by either the staircase or the home's interior elevator. A fourth full bath serves the main level. Outside, expansive decking wraps the rear of the home, stepping down to a covered pergola patio with ceiling fans and room for alfresco dining. Mature irrigated, low-maintenance gardens unfold in layered vignettes. Gravel pathways wind through lavender, rosemary, catmint, and California poppies to a private gazebo; raised vegetable beds; Meyer lemon and Japanese maples; and heritage oaks providing dappled shade. The sub-dividable lot offers generous room for a future pool, guest house, or ADU, a rare opportunity in town where land is at a premium. As the current owner reflects: What we immediately loved is how quiet and peaceful the street is, while still being in the heart of town. The sounds of the river are very soothing a glass of wine on the deck overlooking the river is the ultimate relaxation.
