Enjoy skyline views from your own private 15 x 19 roof deck. This two-bedroom, two-bath penthouse duplex sits atop a classic three-family on a very quiet Cambridgeport street, steps from the Charles River and Magazine Beach. The main level opens into a large entry room, ideal as a dining area, home office, or flex space. The front bedroom has bay windows and an inviting study alcove with custom bookshelves. A second bedroom with pocket doors, a full bath with shower/tub, and a kitchen with a walk-in pantry complete this level. A spiral staircase rises to the top floor, a huge light-filled loft-style space with big-sky views of Cambridge and Boston and its own updated second bathroom with walk-in shower. Highlights of this home include beautiful wood floors; ductless mini-splits for efficient cooling and heating, backed by baseboard heat. An in-unit combination washer/dryer offers convenience, and shared full-size laundry machines are found in the basement, as is a well-appointed exclusive use storage room for unit 3. The Red Line, the Green Line, Whole Foods, Trader Joe's, MIT, and several parks are all close by. A classic Cambridge home.
