Beautiful historic home in one of the loveliest settings in town, with year-round views of Lower Mystic Lake! This gracious upper-level duplex is airy and bright with high ceilings, tons of windows and architectural details at every turn, not to mention a charming deck where you can watch the sun set over the lake. Flexible 11-room floorplan offers a great open living/dining room perfect for entertaining, while the 4 bedrooms, sunroom and 3 studies provide options for home offices, workout space, a reading nook, or other private escape. Top floor master suite offers potential to double the size of the bathroom and expand into the eaves for a massive walk-in closet. Bring your ideas to create the home of your dreams! Other perks include a private basement with laundry, oversized garage plus driveway parking, and a large shared yard. A true sanctuary where you can watch birds (sometimes eagles!) and other wildlife, or get out on the water with your kayak, while still being less than a mile from all the great restaurants and amenities of Arlington Center!
