Commanding breathtaking Atlantic vistas from its privileged eighth-floor setting at Grand Bay Tower, this exceptional residence is a rare offering on the island of Key Biscayne. Originally conceived as a three-bedroom, five-and-a-half-bath home, it has been masterfully reimagined into a grand two-bedroom, three-and-a-half-bath layout, enhancing scale and flow for refined entertaining and effortless daily living. With approximately 3,950sf, the expansive living and dining areas, a welcoming family room, and a bright kitchen with breakfast area are complemented by three terraces totaling about 595sf that are seamlessly integrated throughout the residence. Custom woodwork by renowned designer Juan Montoya enriches the interiors, while the serene primary suite offers a secluded sitting room, bespoke closets and a spa-inspired bath, completing this exceptional oceanfront retreat. One storage unit is included. Separate guest quarters and an additional storage unit are available for purchase separately.
