On the edge of Harvard Square, in iconic Barrington Court, this rare and beautiful floor-through, sixth-floor penthouse overlooks the river and green views. Far above Memorial Drive, the condominium is very close to Harvard Square and the Harvard Business School. 2,138 Sq Ft living area. South-west facing with three exposures and brilliantly sunny, the magnificent residence provides intelligently configured space, all on one level, with fine hardwood floors, many windows, cross-ventilation, a fireplace, and an eat-in kitchen with two exposures. The condominium offers gracious reception rooms, three large bedrooms, a very generous study or fourth bedroom, two full baths, and an in-unit laundry. The handsome sought-after steel-frame elevator brick building dates from 1930. There is a full-time maintenance crew, and the building, which is managed by Thayer and Associates, is kept to a high standard. First appearance on the market in 25 years! Showings by appointment.
