Property Description
Set along a canal in Key Colony Beach, this four-bedroom, two-bath home makes it easy to spend the morning on the boat and the afternoon by your own private pool. Inside, the open kitchen offers ample cabinetry, generous counter space, and bar seating that flows into the dining and living areas. The four-bedroom layout gives guests room to spread out, while the primary suite has its own bath and opens onto a covered deck. A dedicated laundry area adds everyday convenience. Out back, a spacious pool deck and covered entertaining area give you a choice of sun or shade. Rinse off in the outdoor shower after a day on the water, then settle in for dinner by the canal. Mature tropical landscaping frames the backyard, and substantial canal frontage with a seawall, dockage, and a boat lift makes it easy to keep your boat close at hand. With convenient boating access to both the Gulf and Atlantic, you can head out for fishing, diving, or snorkeling right from home. A metal roof, covered parking, and storage round out a property that's equally inviting as a full-time home or a place to get away to the Keys.
