Welcome to Concord Square — one of the South End’s most picturesque cobblestone, tree-lined streets, complete with a working fountain. This parlor-level home in a historic brownstone stands out with its oversized windows, soaring ceilings, and pristine beautiful hardwood floors. The kitchen offers an open layout with granite counters and breakfast bar. Both bedrooms comfortably fit queen-sized beds (& the current primary even has a king!), while the tiled bath has been freshly updated. Additional conveniences include in-building laundry and storage. All just steps from parks, shops, cafés, restaurants, and public transportation in one of Boston’s most desirable neighborhoods.
