Sun-filled penthouse with roof deck plus parking on highly desirable and quiet Mt. Vernon Street in Charlestown! Stunning 1500+ square foot top level Duplex in a beautifully maintained brownstone! Entertainer's dream layout with enormous front-facing living room, dining area and updated chef's kitchen. Viking appliances, high-end cabinetry, breakfast island, and long runs of stone counters make this a truly impressive and functional space! In the rear of the first level is the California King sized primary bedroom with bay windows, walk-in closet and an en-suite bath. Additional half bath off the kitchen, closets, and toweling ceilings! Top floor is the perfect home sanctuary and the layout lends to so many options! Kitchenette area next to the massive roof deck with arguably the best views in Charlestown will be a hit with all! WFH space or additional den area, second bedroom, and an additional full bath complete the top floor. Central air and sparkling hardwood floors throughout, plus the building has a new roof! Wonderful value!
