About This Home
Live every day like you're on vacation in sought-after Knollwood Beach! Lovingly enjoyed by the same family for nearly 50 years, this attractive four-bedroom, one-and-a-half-bath home offers a wonderful opportunity to become part of one of Old Saybrook's most desirable beach communities. Inside, the comfortable floor plan features a welcoming living room with built-in bookcases, and a cozy fireplace that add warmth and character. Sunlight pours into the adjoining sunroom, offering a peaceful retreat overlooking the outdoors. The inviting kitchen is filled with natural light and has been meticulously maintained, featuring warm wood cabinetry, stainless steel appliances, and Corian countertops. A welcoming breakfast nook at one end provides a comfortable spot for morning coffee or casual meals, while the adjoining first-floor laundry room adds everyday convenience and valuable storage. Just off the kitchen, the sun-filled dining room offers a comfortable setting for entertaining and gathering. Updates include a newer roof and heated bathroom floor, irrigation system and vinyl siding. Wood floors lie beneath much of the existing carpeting-ready to be revealed. A brick driveway and walkway wind toward the side entrance, setting a welcoming tone from the moment you arrive. The detached one-car garage and shed adds valuable storage for bikes, beach chairs, umbrellas, and all the essentials for a day by the water. No flood insurance.
