Great opportunity to own a single family (C'1900) in one of Somerville's most desirable locations- on top of Union Sq and close to the Green Line. Urban access yet on a quiet, one-block long, one-way street. Substantial improvements were made during the last five years. With an emphasis on light throughout- the kitchen and dining room were re-designed and a bath (w/ laundry), added. Upstairs, one of the three bedrooms was re-imagined as a skylit studio with a vaulted ceiling. Two additional, generously-sized bedrooms and the common, older bath complete the 2nd floor. A classic, period staircase, hardwood floors and large windows throughout. French doors off of the living room lead to the heated sunroom- the perfect home-office, play-room or "flex" space. Newer roof, exterior paint, an upgraded 200amp panel and gas systems complement the untapped basement with a ceiling height of 7'9". This prime location, a private back yard and driveway complete the package. Welcome to 22 Knapp St.
