Spanning just under 2,100 square feet, this versatile stand alone property is on one of the rare two way streets in Charlestown, alongside plenty of storage space throughout the entire house. It is the perfect setup for savvy investors or owner-occupants looking for premium built-in rental income. Property Highlights. Prime Location: Situated in the highly desirable Gaslight District on a rare, accessible two-way street near local dining, parks, and transit. Stunning Views: Enjoy iconic views of the Bunker Hill Monument and exceptional natural light throughout. Storage & Amenities: Ample storage solutions throughout the house, including built-in wardrobes and shared basement laundry. Outdoor Space: Access to a shared deck and a private backyard oasis, perfect for entertaining. Unit 1 (1 Bed, 1 Bath): Features a large bedroom with a custom built-in wardrobe, bright living space, and direct access to the shared deck and backyard.
