Property Description
Turn-Key Duplex on a Wide, Deep Canal - Key Colony Beach Welcome to one of the most sought-after settings in the Florida Keys -Key Colony Beach -- a private, tucked-away island community known for its quiet streets, boater-friendly waterways, and true Keys lifestyle. This full duplex sits on a impressively wide, clean, deep canal (100 ft across), offering easy access for boats of all sizes and some of the best water views in the neighborhood. Each side of the duplex mirrors the other in quality and layout: upstairs you'll find 2 spacious bedrooms and 2 full baths, while downstairs offers a convenient pool bath plus a bonus game room/flex space with extra storage -- perfect for kayaks, fishing gear, or beach toys.
