This only 18 years young home is designed to assimilate within its historic neighbors yet is elevated with the superior craftsmanship and modern updates. You'll find a well-conceived floor plan that invites both intimate family living and grand-scale entertaining. Notable features: - Bluestone patio overlooking the river for al fresco dining & relaxing - Impeccably landscaped grounds encompassing nearly one acre - En suite bedrooms that promise privacy and convenience for family and guests alike. -Two primary bedrooms; one conveniently located on the first floor - Six fireplaces that provide warmth and ambiance during New England's colder months. - River access for launching kayaks and paddleboards, when the warmer months arrive. Your positioning couldn't be better with your proximity into town, gorgeous views, easy access via backroads to I-95, and walkability of the scenic River Road to which you are at the very start of. This is quite the rare find to have this level of class & comfort in a home with no work needing to be done and numerous benefits being so close to vibrant downtown Mystic and all it has to offer. Own your own piece of history in one of the most prestigious neighborhoods of Mystic. Home is ready for you to turn the key, enter and stay. Nothing was spared with this truly, turnkey home. Lower level just as appealing as the other floors. Plenty of thoughtfully planned, well appointed space.
