The kitchen is equipped with Thermador appliances, and the living room features an electric fireplace. A dedicated mudroom off the entry provides useful everyday storage, complemented by an adjacent bathroom. An attached 2-car garage and heated driveway add another level of convenience. Outside, two private covered bedroom decks and the roof deck provide multiple places to enjoy the home's elevated setting and ocean views.The location puts the beach, Dorchester Heights and neighborhood parks close at hand, along with Broadway restaurants, bars, shops, banking and daily conveniences.
