Tucked behind a lovely private courtyard garden, this airy one-bedroom at 850 Mass Ave puts you in the heart of Cambridge with a surprising sense of calm. Soaring 9-foot ceilings and generously sized rooms give the space an openness rare for the neighborhood, while French doors and original architectural details bring character that newer buildings simply can’t replicate. The kitchen is crisp and functional, with LG and Whirlpool stainless appliances, tile backsplash, under-cabinet lighting and an adjacent dining area. A deeded parking space comes with the unit, along with dedicated storage and card-operated laundry in the basement. This professionally managed pre-war building has a history of careful stewardship in a prime location. Step outside and you’re in the heart of Cambridge in Central Square, with easy access to Harvard Squares, the Charles River, the Red Line and other transit options.
