    A Rare Investment Opportunity in the Heart of Old Town Key West. NIGHTLY rentals allowed. Introducing The Watson House--one of the largest and most versatile TRANSIENTLY licensed estates in Key West. Situated just one block off Duval Street on iconic Simonton Street, this 11-bedroom, 11-bath compound spans two distinct residences: a stately 7-bedroom mansion and a sleek, modern 4-bedroom villa--each with its own private pool.Zoned with two transient licenses and off-street parking for 4+ vehicles, this exceptional property offers unmatched flexibility for luxury rentals or private use.The grand mansion was reimagined in July 2022 by a local designer, featuring fresh paint, stylish new furnishings, and 12-foot soaring ceilings. The main level includes two guest rooms with baths, formal living and dining rooms, a parlor, and a well-appointed kitchen that opens to the pool deck and outdoor dining area.Upstairs, four en suite bedrooms include two primary suites with private balconies--one overlooking Simonton Street, the other with views of the pool. A spacious third-floor suite, accessed via an interior or exterior staircase, offers a private living room, wet bar, and yet another balcony retreat.The villa, renovated to the studs in 2014, offers a clean, contemporary design with 4 bedrooms, 4 baths, full kitchen, living area, private pool, and outdoor bar--perfect for entertaining.Whether you choose to rent the estate in its entirety or as two separate homes, The Watson House is a rare asset in Key West's luxury rental market--highly sought-after and consistently booked well in advance.
