Holding a coveted TRANSIENT LICENSE allowing profitable nightly rentals, this turnkey Old Town sanctuary sits just a half-block from world-famous Duval Street while enjoying a prime position near boutique shops, fine dining, and the Southernmost Point. Step inside through iconic yellow doors into a bright, sunny retreat defined by historic Dade County pine walls, gingerbread balustrade details, high soaring ceilings, and rich natural light.

The interior layout offers total comfort and privacy for guests. The main floor houses two king-bedroom suites complete with walk-in showers, including one with direct access to the poolside sanctuary. Tucked upstairs for added seclusion, the third ensuite bedroom features a queen bed, vaulted ceilings, and sunny exposure. Completely renovated with impact windows, and dedicated off-street parking, this property is designed for effortless ownership. Whether retained as a high-performing vacation rental with proven revenue projections or enjoyed as a private island getaway, this home offers a rare chance to own a piece of Key West paradise.
