About this House
Always dreamed of owning a private island retreat? This is a once in a lifetime opportunity to own a piece of the legendary Mouse Island. A storybook location at the mouth of the Mystic River- just off the coast of Noank Village and the Morgan Point Lighthouse, with Groton Long Point to your west, Fishers Island to your south, and Ram Island to your east. This totally green off-the-grid island home will provide you the oasis retreat you’ve been seeking. Land is within sight and you are close to everything Mystic and Noank have to offer, while enjoying the privacy of an island accessible only by boat. Four bedrooms and lovely cottage furnishings, all in excellent condition. Panoramic water views from every room: the first floor is open plan, and includes a large family kitchen, dining area, living room with working fireplace, and full bathroom with shower. The second floor has four comfortable bedrooms, and sleeps eight. Shaded by trees with an east-facing porch for a sunrise coffee, and a west-facing porch for sunset cocktails. All furnishings are included (Adirondack chairs, appliances, generator, and household furniture), as well as an Eastern 18' skiff with Honda four stroke 50 horsepower motor for transport, exploring the harbor, trips up to Mystic, or hopping over to Abbott's or Ford's for a legendary seafood dinner. Lovingly cared for and in excellent condition it's ready to enjoy from day one! The pleasures of island living - watching egrets graze the tidal pools, toasting s’mores by the fire pit, and casting for striped bass off the back rock - are irresistible. This residence is a one of a kind find. Video -> https://rem.ax/420BbXS
