Encompassing an impressive 7,400 square feet under A/C, this exceptional residence offers breathtaking panoramic views of the Atlantic Ocean, Biscayne Bay, and the Miami skyline.

Beautifully upgraded and designed for both grand entertaining and comfortable living, the residence features expansive living areas, an elegant formal dining room, gourmet kitchen, and private home theater. The magnificent primary suite is a true private sanctuary, featuring a generous walk-in closet and two separate, beautifully appointed bathrooms, offering the ultimate in comfort, privacy, and luxury. Three additional spacious bedrooms, each with its own en-suite bathroom, provide exceptional comfort and privacy. Residents enjoy an extraordinary resort-style lifestyle with direct beach and ocean access, concierge and valet services, a state-of-the-art fitness center, a spectacular swimming pool, and the impeccable service of Grand Bay's dedicated professional staff. A rare opportunity to own a truly remarkable penthouse where space, sophistication and breathtaking views capture the best of this island.
