This exquisite 4-bedroom, 3-bath retreat masterfully blends SOPHISTICATED LUXURY, serene relaxation, and exhilarating adventure at the epicenter of the Florida Keys. Enter your private oasis bathed in perpetual sunshine. Recline beside the sparkling PRIVATE SWIMMING POOL or indulge in a refreshing plunge to escape the warmth. The meticulously crafted OUTDOOR ENTERTAINMENT enclave invites endless indulgence: a full-size bar complete with refrigerator, dedicated bait freezer, and gourmet grill for sublime al fresco dining. Unwind beneath tropical breezes in the outdoor lounge for cinematic evenings, or gather around the fire pit under a canopy of stars for intimate marshmallow toasts. Ignite friendly rivalry with cornhole or billiards, then set forth on serene kayaking explorations. Conclude each day in transcendent splendor on the upstairs screened porch, offering unobstructed panoramic vistas of the Keys' captivating beauty and legendary sunsets.

Secure your vessel at the exclusive 30 FOOT PRIVATE DOCK equipped with a fish-cleaning station for effortless preparation of the day's bounty. This privileged access grants swift passage to both the Atlantic Ocean and Gulf of Mexico via the picturesque Sisters Creek. Snorkeling enthusiasts will revel in the nearby vibrant coral reefs of Sombrero Light--a short voyage to an underwater living aquarium teeming with marine splendor. Within, discover a beautifully renovated residence engineered for supreme comfort, highlighted by two luxurious master suites each graced with indulgent king beds--offering secluded sanctuaries.
