About this home
On the corner of Gloucester and Commonwealth Avenue, this floor-through Back Bay classic offers direct elevator access and checks all the boxes. Sprawling living area with wood-burning fireplace, soaring ceilings and oversized bay windows frame the Commonwealth Avenue Mall and flood the space with natural light. The formal dining room is beautifully appointed and features built-ins and its own fireplace. The bright kitchen offers a dishwasher, double wall ovens, countertop range and subzero refrigerator. The Primary suite showcases generous proportions with room for a sitting area, multiple closets, and an ensuite bathroom. The secondary bedrooms share a full bath with a standing shower with glass enclosure. Deeded parking and extra storage complete this offering. Set within the historic Charles Francis Adams Mansion, once home to the grandson of President John Adams, this is one of Boston's most coveted addresses, moments from the city's best restaurants, shops, and parks.
