This penthouse duplex, offering 2 beds plus a generous den and a private roof deck, sits discreetly tucked on one of Back Bay's beloved side streets in a low-stoop brick rowhome-a rare opportunity to enjoy penthouse living without the penthouse climb. Upon entering, you are welcomed into a spacious foyer with room for all the coats and boots New England's seasons require. Around the corner, a beautifully appointed kitchen offers island seating, plenty of counter space and abundant cabinet storage. The kitchen flows seamlessly into the dining area and unfolds into the fireplaced living room, where skyline views and custom built-ins add both beauty and storage. Before heading up the custom staircase, strikingly set against exposed brick, you'll find a half bath and a sizable den that shares the same city views.The upper level features the primary bedroom with a vaulted wood-plank ceiling, an outfitted walk-in closet and a dual-entry full bath, accessible from both the bedroom and the hall. The second bedroom, with custom closets and eaves storage, sits next to the renovated second full bath. Thoughtful luxuries abound: double ovens, heated bathroom floors, a heated towel rack, and wine and beverage coolers tucked into the hall storage, perfectly placed for entertaining on the private roof deck. Large enough for both lounge and dining areas, the deck is ideally situated for Fourth of July fireworks and offers a year-round treetop perspective. Rounding out the home are in-unit laundry, common laundry and storage in the basement, a transferrable rental parking space nearby and a recently installed high-efficiency HVAC system, in a 100% owner-occupied building. All of this sits a block from the Commonwealth Avenue Mall and less than two blocks from Newbury Street's boutiques, restaurants and cafes, with The Prudential Center, the Esplanade and Fenway Park all nearby. Commuters enjoy quick access to the Mass Pike and Storrow Drive. This is Back Bay living at its best.
