Description

Professional Pictures are coming soon. A Private Waterfront Love Story in the Florida Keys Welcome to Key Lime Kottage, where the moment you arrive, life begins to slow down. Vacation Rental Property, tucked behind lush tropical privacy in Grassy Key, this romantic waterfront retreat feels less like a house and more like your own private resort. The soft yellow cottage, the metal roof, the white picket charm, and the quiet setting invite you to exhale before you even open the front door. Then the water calls you. A beautiful composite dock leads you gently through the mangroves toward open Gulf views, where the sky feels endless, the water glows in shades of blue, and every sunset feels like it was painted just for you. Imagine walking hand in hand to the dock with your morning coffee, watching the stillness of the bay, or sitting there in the evening as the day melts into gold. The heart of this property is the extraordinary screened outdoor living area. Here, the pool and spa become your private sanctuary -- a place to float under the filtered sunlight, enjoy dinner beside the water, lounge with a book, or gather with the people you love. The surrounding mangroves create natural privacy, giving vacationers that peaceful resort feeling they return for again and again. Inside, this 3-bedroom, 2-bath turn-key waterfront home is warm, welcoming, and ready for immediate enjoyment. The open living, dining, and kitchen space creates an easy flow for family, guests, and unforgettable Keys memories. Every detail feels effortless -- designed for relaxation, comfort, and connection. For those seeking income and lifestyle, Key Lime Kottage offers the rare combination buyers dream about: a successful weekly vacation rental, a private waterfront setting, a pool and spa, Gulf views, and a location close to the Dolphin Research Center, The Wreck Restaurant, downtown Marathon, grocery shopping, entertainment, marinas, and MillionAir.
