Inside, a bright two-story layout unfolds with an open, airy feel, thoughtfully designed for both everyday comfort entertaining. The residence features five bedrooms, four full bathrooms, plus a cabana bath, all flowing seamlessly enhanced by abundant natural light and tranquil water views. Renovated in 2019, the home includes impact windows and doors, a beautifully updated kitchen and appliances, lighting throughout, gas generator, and a pool heater and chiller for year-round enjoyment. The outdoor living experience is truly exceptional…enjoy direct water access with a private dock, boat lift, and two dry jet-ski docks, allowing you to step straight from your backyard to open water and fully embrace the waterfront lifestyle. A detached, enclosed two-car garage adds versatility, while the gated property offers abundant parking for up to six vehicles, a rare and valuable amenity in Key Biscayne.
