2 Ellery Square is a delightful sunlit attached single-family townhouse in the heart of Mid-Cambridge, with over 1900 square feet of contemporary-style living space. Each of its four bedrooms has its own level; two have en-suite full bathrooms. The design embraces nature in the city: oversized windows let morning and afternoon light stream in, the two-story living room overlooks a private patio, and the main bedroom connects to a sunny top-floor deck. Inside, clean lines and an open plan give a sense of spaciousness, with hardwood floors in the main rooms and new carpeting on the stairs. Either or both of the two middle bedrooms could make an excellent office, study, or media room, while the downstairs bedroom suite would be ideal for a guest or nanny. The property is perfectly located, not far from Harvard, Central, and Inman Squares and across Broadway from the award-winning Cambridge Public Library. Attached garage parking, a well-run homeowners’ association.
