This charming 3-bedroom, 2-bath half-duplex has so much to offer! Watch stunning Keys sunsets from your screened porch, or dock your boat at the 30-foot slip with quick ocean access just around the corner. Stroll to the Cabana Club for pool and beach access down the street. The master suite features a king bed, a bath with a jetted tub, separate shower, double sinks, and a walk-in closet. The guest rooms offer a queen bed and two full beds. The home comes fully equipped with three Smart TVs, Wi-Fi, and cable. Outside, enjoy a fish cleaning station, bait freezer, BBQ, picnic table, and more. You're within walking distance of all KCB's attractions--parks, restaurants, golf, and more. Key Colony Beach sits in the heart of the Florida Keys near Marathon airport, about 50 miles from Key West and roughly 90 minutes from Miami-Dade. With direct access to both the Atlantic and Gulf, plus nearby coral reefs, fishing, and diving spots, it's the perfect vacation getaway and one of the Keys' best-kept secrets!
