Welcome to the Penthouse Residence at 128 Marlborough Street, a stunning, fully renovated duplex residence that blends classic Back Bay elegance with modern luxury. A gracious entry foyer leads to a sun-drenched living and dining area with a gas fireplace and oversized windows. The chef’s kitchen features a large marble island, Sub-Zero fridge, Wolf appliances, and custom cabinetry. Upstairs, the spacious primary suite offers a custom walk-in closet and a luxurious marble bath with a soaking tub, double vanity, and glass shower. Two additional bedrooms, one of which currently functions as an office, share a full bath and in-unit laundry. A dramatic spiral staircase topped by a skylight leads to the crown jewel: an expansive private roof deck with built-in Wolf grill, four refrigerated drawers, and 360-degree city views. Located on one of Back Bay’s most coveted blocks, 128 Marlborough offers the rare opportunity to own a beautifully renovated home with unbeatable outdoor space.
