Home in 16 Seaside Avenue, Key Largo, FL 33037 for sale with MLS# A12043189

This extraordinary 7-bedroom, 7 full and 2 half-bath residence offers luxurious living designed for effortless entertaining and multi-generational enjoyment. From the moment the private gates open, a fully integrated smart home system seamlessly controls the estate--from the front entrance and security system to interior lighting, climate, surround sound, and even the dock lighting--creating a level of convenience rarely found in waterfront homes. A commercial elevator services all three levels, while a whole-house generator provides peace of mind year-round. With everyday living in mind, the home features 2 dedicated laundry rooms for the upmost functionality. Every bedroom serves as a private retreat, complete with its own spa-inspired ensuite bathroom, spacious walk-in closet, and custom built-in closet system. Expansive open living areas are filled with natural light and thoughtfully designed to maximize breathtaking Ocean views. Outdoor living rivals that of a private resort. The spectacular oceanfront pool, spa and waterfall, gazebo, outdoor kitchen, and integrated indoor/ outdoor surround sound create the perfect setting for entertaining. A private sandy beach and pier provide an idyllic place to enjoy sunrises over the Atlantic, while the rooftop observation deck captures panoramic ocean views of both the ocean and bay. Best of all this property offers the ability for short term 7-Day rentals!
