A bright yellow door sets the tone at 7 Sparks Street: cheerful, sunlit, and full of welcome. Near the Charles River, Harvard Square, the Cambridge Tennis Club and Cambridge Skating Club, this thoughtfully designed single-family delivers a complete Cambridge lifestyle. With four bedrooms, two full baths, a half bath, and 2,244 SF of finished space, every level works hard. The first floor is open and sunny, with a handsome kitchen, dining area, and living room anchored by a terracotta-tiled fireplace. Glass doors open to the backyard’s happy surprise: a generous fenced setting with brick patio, lawn, and shed for bikes and gear. Upstairs, the calm primary bedroom has a walk-in closet, while the second bedroom and well-composed shared bath complete the floor. Two top-floor bedrooms add flexibility for family, guests, work, or play. The lower level adds gym, laundry, storage, and a hangout zone. A bricked driveway completes this fantastic powerhouse of great design and terrific utility.
