Condo for sale in Boston, MA

for $1,350,000 with 2 bedrooms and 2 full baths. This 1,232 square foot condo was built in 1900 on a lot size of 0.03.

Long before Boston’s waterfront traded cargo ships for cappuccinos, before the skyline shimmered and the Harborwalk traced the edge of the sea, this stretch of Commercial Street moved to the rhythm of ships, trade, and salt air. As the city reinvented itself, so did this storied building, evolving into The Mariner and trading industrial hustle for luxury waterfront living where Residence 507 has a front-row balcony seat to Boston’s skyline glow-up. A home that lives at the intersection of history and happy hour. Here, mornings begin with harbor sunrises and caffeinated dog walks along the water, afternoons invite spontaneous strolls through the North End’s timeless streets and the Waterfront’s green open spaces, and evenings unfold somewhere between harbor breezes, the hum of dining rooms with “just one more” espresso martini and the glow of the city skyline. This is a home shaped by movement, by stories layered over time, and by the unmistakable energy of urban coastal living.
