About 15 Sunnyside Avenue

Opportunity awaits on this picturesque side street nestled in one of Darien's charming neighborhoods. Originally built in 1926, this impeccably maintained Colonial sits on a lovely, level lot, complete with a fully fenced backyard, professionally landscaped gardens and stone patio. The home seamlessly blends timeless vintage character-including thoughtful millwork, custom built-ins, and antique hardwood floors throughout-with the contemporary functionality of an updated kitchen and two renovated full baths. Generous walk-through living and dining rooms offer flexible space, with a sunlight filled den/ office rounding out the first floor. Upstairs, three generously sized bedrooms offer comfort and privacy, while thoughtfully finished spaces in both the basement and attic provide versatile options for work or leisure. A large, detached two car garage offers yet more storage. Ideally situated near Holmes Elementary and Middlesex Middle School, as well as Woodland Park, the property affords easy access to Noroton Heights Train Station and the vibrant new Darien Commons and Heights Crossing shopping districts, further elevating the convenience and allure of this exceptional home.
