Meticulously renovated in 2025, this exceptional penthouse duplex seamlessly blends the timeless elegance of Back Bay architecture with the comfort and sophistication of modern living. Offering direct elevator access to both levels, the residence encompasses over 3,000 square feet of thoughtfully designed living space.

Oversized glass doors open directly onto a private walk-out deck, creating effortless indoor-outdoor living, while a separate private roof deck offers sweeping Boston skyline views. The lower level features three spacious bedrooms, two full bathrooms, and a versatile lounge framed by custom built-ins, creating a flexible space for a family room or home office. Additional highlights include two deeded parking spaces, wired for surround sound, and a pet-friendly association.
