Set on the sunny side of Commonwealth Avenue, this rarely available 2,660 square foot duplex offers exceptional space within one of Back Bay's most sought-after buildings. The main living level features a spacious, sun-filled living room with high ceilings, hardwood floors, and beautiful period detail, along with a well-appointed kitchen, a separate bonus living room or den, and a dedicated office space for flexible day-to-day living. The upper level is anchored by a generous primary suite with a Juliette balcony and en-suite bath, while the second bedroom is located on the lower level, offering privacy and separation. Additional features include a private patio, two garage parking spaces, and additional storage. Ideally located just moments from the Public Garden, Newbury Street's premier shopping and dining, and the Green Line, this is a rare opportunity to live on one of Back Bay's most desirable stretches of Commonwealth Ave. Can be furnished or unfurnished.
