Description

Welcome home to Boston's waterfront at The Mariner, where the comforts of a full-service elevator building meet harbor living. This inviting one-bedroom residence features an open-concept main living area with high ceilings that flows out to a private, covered balcony, the perfect spot for morning coffee or hosting with a view of the city skyline. Other defining features include central air conditioning, in-unit laundry, and recessed lighting. Residents of The Mariner enjoy 24-hour concierge service, plus access to an oversized, furnished common roof deck with sweeping panoramic views of Boston Harbor. Originally built in 1911 and converted to condos in 1987, the building itself carries the character of Boston's storied waterfront. Recent noteworthy capital improvements within the association include a new cooling tower and boiler, roof, exterior façade coating, and an updated lobby and hallways. Improvements within the unit include a new HVAC system (2023), refrigerator (2023), and dishwasher (2023), washer and dryer (2022). Ideally located just steps from the Historic North End harborwalk, Hanover Street restaurants, the Financial District, and TD Garden. Pets are permitted with trustee approval.
