About this home

Perched beside the State House and Boston Common, The Bellevue blends timeless grandeur with urban convenience in a professionally managed elevator building. Residents enjoy a spectacular common roofdeck with sweeping skyline views, a glass enclosed rooftop function room, concierge service, and a striking skylit lobby. On-site management, daily maintenance, and floor-by-floor laundry and trash rooms add effortless functionality. This distinctive unit features curved glass windows, soaring ceilings, decorative moldings, an ornamental fireplace, chandeliers, and original parquet floors. The bedroom offers a mirrored sliding-door closet with rare vertical expansion potential, while custom millwork—original to the hotel—lines the entry. Seller welcomes offers with requests for buyer concessions.
