Adorable Colonial in terrific location near Thoreau School. Very peaceful, yet easy trip to commuter rail and W. Concord center. Walking path at the end of the private road to Thoreau School & playground. You'll be wowed by the hardwood floors. Heated space on 3rd floor not included in sqft. Tremendous charm and potential in a small gem. Seasonal river views.
