Perched on the third floor of a classic Cambridge building at the end of a rare cul-de-sac, this light-filled treetop penthouse—meticulously renovated in 2019—offers a tranquil retreat just moments from Central Sq. The home features two bedrooms, a full bath, and a versatile loft alcove—perfect for a home office, guest space, or creative retreat—framed by exposed beams and five southeast-facing, solar-powered Velux skylights. Solid ash floors, solid-core doors, and premium Schoolhouse finishes run throughout. The chef’s kitchen includes natural soapstone countertops, designer tile backsplash, 36” Wolf dual-fuel range, Kohler Prolific sink, eat-in island, and a large picture window. The open layout flows into sunny living/dining area and out to a private deck perched above the trees. With high-efficiency HVAC, in-unit laundry, parking, low HOA, and 100% owner occupancy, this move-in-ready home sits just blocks from the Red Line, Whole Foods, and all the vibrants offerings of Central Sq!
