About this home

Hidden in plain sight! In the Baldwin neighborhood, near Porter, Lesley, Harvard, and steps from Giulia, Simon’s, Bagelsaurus, and Honeycomb Creamery. Tucked on a leafy one-way street, this standalone townhouse blends privacy, light, and smart design. Built in 1987 and recently reimagined by Square House Studios, the kitchen hits all the marks: Porcelanosa cabinetry, farmhouse sink, Ann Sacks tile, and clever storage. Floor-to-ceiling windows wrap the living space and open to a large private deck and fenced patio and garden. Upstairs, the primary suite offers a calm retreat with its own balcony, dressing room/closet, and beautifully finished bath. A second bedroom with Juliet balcony and en suite bath completes the floor, while two bright top-floor bedrooms and another full bath offer tremendous utility. Garage + driveway parking round out this rare find. Easy access to Red Line T, Downtown Boston, Route 2 and I-93.
