About This Home

Tucked away on a quiet private enclave just steps from iconic Sombrero Beach, this open-water retreat offers stunning ocean views and an ever-changing palette of turquoise and deep blue waters. Located on exclusive Treasure Road, this is a setting you only drive down if you live there, peaceful, private, and perfectly positioned just moments from the sand. The home features 3 bedrooms and 3.5 baths, with approximately 2,300+ sq ft of living space on an almost 12,000 sq ft lot, including 77 feet of concrete seawall and approximately 89 feet of waterfront. The primary living room showcases high ceilings and expansive sliding glass doors that open directly to incredible open-water views, filling the space with natural light and creating a seamless indoor-outdoor connection. Sunset views stretch across the water, while mature tropical landscaping, shady trees, and a heated 15' x 30' concrete pool create a true island oasis. Each bedroom is an ensuite, offering comfort and privacy, with an additional half bath conveniently located near the pool. The home has wonderful character, a second living area downstairs, a covered lanai ideal for outdoor dining and relaxing, and an upstairs sun deck perfect for soaking in ocean views and sea breezes. Additional features include a circular driveway, garage, and generous outdoor space for entertaining or unwinding. This golf-cart-friendly, family-friendly neighborhood allows you to bike, walk, or run to the beach, grocery store, and some of Marathon's best restaurants, truly one of the most desirable areas in the Keys. Enjoy community events hosted at Sombrero Beach, including the renowned Fourth of July celebration and fireworks. This property has never been rented, though weekly vacation rentals are allowed. A rare offering in one of Marathon's most sought-after neighborhoods, where ocean views, privacy, and the island lifestyle come together effortlessly.
