Classic 1920s two-family with third floor expansion enjoys all the conveniences of its East Watertown/Mount Auburn location. Just moments to Arsenal Street and Watertown Square, and within easy reach of Cambridge, this fully owner-occupied property retains an abundance of original character-defining details: wood floors, built-ins, and millwork. The first floor unit is a 5rm/2bd/1ba, while the upper unit spans two floors with 7 rooms, 4 bedrooms, and 2 full baths, has front and rear balconies, and attic storage. There is interior and exterior access to the unfinished basement, which has good ceiling height, laundry, and plentiful space for storage. Separate systems and updated electrical. The sweet yard is fully fenced and there is parking for 4 cars off-street. A thoughtfully maintained and charming property in a great location.
