Rich in historic character and offering an impressive approx. 3,360 square feet across four levels, this classic 1880 Charlestown brownstone delivers exceptional scale and versatility. The main and upper levels function as an expansive single-family home, with elegant living and dining rooms, an updated kitchen, soaring ceilings, intricate millwork, hardwood floors, oversized windows and four fireplaces. The expansive primary suite is a standout, complete with custom built ins, a fireplace and spacious en-suite bath with dual vanities, soaking tub and glass-enclosed shower. The top floor also offers the potential to be reconfigured into two bedrooms, adding an additional bedroom to the home. A private deck and patio extend the living space outdoors.

Convenient to Main Street and all Charlestown has to offer, with easy access to Downtown Boston, the waterfront and major highways.
