Welcome to PORT45, a luxury condominium building ideally situated at the crossroads of South Boston, the South End, and Seaport. This beautifully appointed two-bedroom, two-bath residence offers an inviting open layout, contemporary finishes, and a wonderful sense of privacy, with oversized walls of windows overlooking a lush canopy of mature trees.

The generous primary suite comfortably accommodates a king-sized bed and features a large walk-in closet and en-suite bath. The second bedroom offers exceptional flexibility with a built-in Murphy bed, allowing it to function as both a home office and a guest room, or it could easily accommodate a queen-sized bed.
