A classic top-floor condo in the heart of mid-Cambridge, 55 Ellery Street #3 has been well loved by its owner since the 6-unit building was converted in 1979. The wide living room is bathed in light, with hardwood floors, closets, and just the spot for a home office. Off the central hall are two well-proportioned bedrooms and a skylit bathroom with a striking tile floor, clawfoot tub, and exposed brick wall. The kitchen, renovated in 2004, features stone counters, a combined washer/dryer, glass-front cabinets, and a handy pantry. A west-facing covered deck is a perfect place to feed the birds, read a book, or grow some flowers and herbs. The fenced back yard is common, with a brick patio, mature plantings, and easy access to the street. Private basement storage. A new roof went on in 2022, and the building is professionally managed. The neighborhood boasts the best of Cambridge: the main library, CRLS, the Red Line, and the shops and restaurants of Harvard and Central Square
