Sun-flooded penthouse perched on a gaslit cobblestone street on one of Charlestown’s most sought after blocks, just steps from the Bunker Hill Monument. Spanning nearly 1,400 square feet on a single level, this rare standalone building is wrapped in 15 windows on all sides, flooding the home with exceptional natural light from sunrise to sunset. The expansive open floor plan offers proportions rarely found in Charlestown, while unobstructed views of Downtown Boston, the Harbor, and Back Bay create a dramatic backdrop to everyday living. The updated kitchen features a breakfast bar and abundant storage. The spacious primary suite is a private retreat, complete with a renovated en suite bath featuring a double vanity, frameless glass shower, and soaking tub. Crowning the home is a spectacular PRIVATE ROOF DECK with sweeping 360-degree views of the Boston skyline, Harbor, Monument, and beyond. Central air and generous basement storage complete this truly exceptional offering.
