Introducing the Penthouse at 122 Commonwealth Avenue, one of just three exclusive residences in a magnificently renovated brownstone in Back Bay. The Penthouse is the epitome of luxury, encompassing the top two levels of this extra wide townhouse; offering a rare opportunity to own over 4,000 square feet with direct elevator access. The Penthouse features three bedrooms and three-and-a-half bathrooms with grandly scaled living, dining and entertaining spaces plus a large walkout terrace with floor to ceiling windows off the living area and a spectacular private roof deck. This residence has been meticulously constructed with unerring attention to quality; every detail and finish-from the gourmet kitchen to the spa-like marble baths-is top-of-the-line and befitting of such a fine address. The Penthouse is complete with two on-site parking spaces, all on a highly desirable block of Commonwealth Avenue.
