80639 Old Highway 309 Set within a private gated enclave, this top-floor, corner unit captures the essence of Islamorada living. Quietly elevated, effortlessly refined, and deeply connected to the surrounding seascape. Positioned to embrace sweeping Atlantic Ocean views and the iconic Alligator Reef Lighthouse, expansive walls of glass invite natural light and open water vistas into nearly every space, including each bedroom and even the baths. Thoughtfully updated with a clean, modern aesthetic, the residence balances comfort with simplicity. A minimalist kitchen appointed with Bosch appliances flows into open living spaces designed for relaxation, complemented by floating bathroom vanities, recessed lighting, blackout blinds, owner and storage closets, and carefully considered modern finishes. One of the few properties in Islamorada permitting extremely rare weekly rentals, this offering provides uncommon flexibility for both personal use and investment ownership. Beyond the residence, the community unfolds as a peaceful coastal retreat featuring a white sandy beach, resort-style pool, bocce courts, swimming pier, kayak and paddleboard launch, and a cocktail dock where the rhythm of island living naturally unfolds. The covered oceanfront balcony captures steady year-round breezes and uninterrupted views across the Atlantic. Several nearby full-service marinas provide convenient access for effortless boating throughout the Keys. Just down the Old Road, Gibb Reese Park offers open green space, shaded playgrounds, pickleball courts, gathering areas, and community amenities that enhance everyday living. Located minutes from renowned Islamorada dining, boutique shopping, and the Morada Way Arts District, Maison provides seamless access to the destination's most sought-after experiences while maintaining privacy within a boutique waterfront setting. A residence defined not by excess, but by serenity, exclusivity, and connection to one of the Florida Keys' most iconic landscapes.
