This sophisticated penthouse is sited within an architecturally significant building, and fully renovated for urban dwelling. Constructed in 1887 at the corner of Mass Ave & Lee Street, the building was moved to its current location in 1898 (Cambridge Historical Commission). Upon entering, you are greeted by an awe-inspiring living/dining area with a soaring vaulted ceiling with two skylights, a built-in window seat & bookshelves, and charming wood stove, all accented by antique cabinetry. There is also a walk-in storage closet. The updated kitchen showcases custom cabinetry, a stainless-steel gas stove, and skylight. The spacious primary bedroom features a walk-in closet, additional closet, and door to the treetop porch. There is a second bedroom with a skylight, and large hall bath. The best part - outside there's a secret spiral staircase to a massive private deck among the trees. Located within a 1/2 mile radius of Harvard, Joan Lorentz Park, Public Library, and The Charles River.
