A perfect blend of timeless charm and modern comfort, this beautifully upgraded Balboa Island cottage is ideally situated on the 100 Block, near the one of the best sandy beaches on South Bayfront. A four bedroom, two bathroom original "Yale House" home, lovingly maintained by the family since 1951, and on the market for the first time since, it offers the quintessential Island lifestyle in one of the most desirable locations. Tucked behind a classic front gate and lush, mature landscaping, the sun-drenched front yard welcomes you into a storybook setting. Whether hosting friends, sipping morning coffee, or simply soaking in the daily Island buzz, this private outdoor space captures the essence of relaxed seaside living. Inside, the home embraces its original cottage character while offering tasteful modern updates. Enjoy the warmth of hardwood floors, handcrafted built-ins, refreshed bathrooms, and a beautifully remodeled kitchen-all thoughtfully integrated to preserve the home's cozy coastal spirit. The floor plan is equally inviting, featuring a spacious downstairs primary suite and open-beamed living areas ideal for gatherings with family and friends. Private parking in the rear provides rare convenience on the Island, while the home's proximity to the bay, beaches, and Marine Avenue shops and dining makes it an unbeatable location for full-time living or a part time getaway.
