About this home

Worthy of Architectural Digest, this wonderfully renovated two bedroom, two bath condominium at the Milldam is Concord Center living at it's finest! Thoughtfully redesigned to create a sophisticated living space, the European inspired kitchen boasts beautiful new cabinets, appliances, and storage. Open to the kitchen are spacious dining and living areas with ten foot ceilings and a marble fireplace surround re-purposed from a venerable Beacon Hill townhouse. The unit boasts a magnificent East facing tree-top balcony with long, unobstructed views, two deeded parking spaces, a private storage unit, and access to lovely common areas. Just a short stroll to restaurants, shopping, museums, and the train to Boston and Cambridge, this condo truly has it all!
