Rarely does Porter Square offer this: 3,468 sq ft of contemporary living on four finished levels and a private, fully fenced backyard, newly landscaped with an expansive paver patio. Inside, the open living/dining space is anchored by a linear gas fireplace framed by custom built-ins, with a sunlit sitting area, white oak floors, and sliders opening directly to the backyard. The chef's kitchen pairs Sub-Zero and Wolf appliances with a waterfall quartz island, European-style cabinetry, and a glass backsplash. Upstairs, the primary suite features double closets and a spa-inspired bath with freestanding tub, rain shower, and dual vanity; two additional bedrooms and a full bath complete the level. The third floor is its own private suite: a fourth bedroom with separate living area and full bath. The finished lower level offers a family room, dedicated office, full bath, and laundry. Thoughtful amenities include six zones of central A/C, heated bathroom floors, EV charging, and two deeded off-street parking spaces. All just six minutes on foot to Porter Square, nine to Davis Square, and 1.1 miles to Harvard. The space and privacy of a suburban home, in the heart of Cambridge.
