Welcome to this four-level, semi-attached single-family home on a sun-filled corner lot on South Boston’s coveted East Side. Corner exposure brings abundant natural light throughout, and side-by-side off-street parking for two cars is a true luxury in this neighborhood. The home offers four bedrooms and two and a half baths spread across four stories. Thoughtful separation between levels gives you room to live, work, and host. The main living level flows easily for everyday life and entertaining, and the bedroom levels offer comfort and privacy. At the top, a private roof deck is an outdoor retreat for morning coffee, summer evenings, and city and sky views. The location puts you a short walk from Castle Island, Pleasure Bay, M Street Beach, and the shoreline paths, along with East Broadway’s restaurants, cafés, and shops. Commuting downtown and to the Seaport is easy. A corner single-family on the East Side with two-car side-by-side parking and a roof deck is hard to find. Schedule your showing today.
