Description

Virtually Staged. Positioned directly on the pristine sands of Treasure Island, The Marquesa represents a rare, Mediterranean-style boutique enclave of only 17 private residences. This exceptionally curated 3-bedroom, 3.5-bathroom sanctuary balances understated coastal sophistication with gallery-like spatial proportions. Bathed in natural light, the open-concept living environments unfold seamlessly, framed by floor-to-ceiling glass that invites the shifting colors of the Gulf of Mexico indoors. The floor plan is well designed for entertaining, yet affords privacy. A grand primary suite overlooks the water, offering a waking vista of the horizon, walk-in closets, and a spacious en-suite bath. Each additional guest bedroom features its own dedicated en-suite bath, providing secluded accommodation away from the main living areas. The kitchen balances high design with functionality. Step outside to an expansive private terrace to capture sea breezes and unforgettable Gulf sunsets. Impeccably maintained grounds feature a heated beachfront pool, boardwalk to the sand, an individual ground-floor garage, and controlled access. Positioned safely back from Gulf Boulevard yet moments from boutique dining and shopping, this property serves as a timeless legacy asset or private coastal retreat.
