Penthouse living reaches new heights in this meticulously restored Chester Square brownstone in the heart of the South End. Spanning the top two floors, this three-bedroom residence opens through a grandly scaled foyer rich with period detail. The bedroom level features a generous primary suite with dramatic ten-foot ceilings, a decorative marble fireplace, and a spacious walk-in closet, while a second bedroom offers a beautiful bow front window and its own marble fireplace. A third room provides flexibility as an office or guest space. Brazilian cherry floors lend a warm, rich ambiance throughout, complemented by renovated marble bathrooms. Upstairs, vaulted ceilings and skylights crown a vast open living space anchored by a full wall of floor-to-ceiling built-ins, with arched windows framing the skyline above the dining area. The chef's kitchen showcases elegant marble counters, and a private roof deck caps the residence with sweeping panoramic city views.
