12399 Overseas Highway 12 Imagine arriving in the Keys, dropping your bags and heading straight out on the boat. That's the beauty of life at Coral Lagoon, where the NEW DOCKS ARE COMPLETE and your deeded 40' dock space awaits just steps from your back porch. This beautifully remodeled townhome offers plenty of room to unwind after a day on the water. The main level is open and welcoming, with high ceilings, an updated kitchen and breakfast bar, comfortable living and dining spaces, a powder room and a deep covered porch overlooking the canal. Upstairs, the primary suite is a private retreat with vaulted ceilings, an ensuite bath and its own waterfront balcony. Two additional bedrooms, a guest bath and laundry provide comfortable accommodations for family and friends. Prefer a day by the pool? The community's heated swimming pool is ready to enjoy. Need fuel before heading offshore? The Boat House is right next door, with easy access to both the Atlantic and Gulf. Restaurants, bars and shops are also just a short walk or bike ride away. Currently an active vacation rental, this property requires advance notice for private showings.
