A quintessential Upper East Side prewar cooperative erected in 1918, the nine-story building comprises roughly 30–36 residences ranging from modest one- to expansive five-bedroom configurations. The façade and common spaces retain traditional period details; inside, apartments commonly feature high beamed ceilings, oversized windows, working wood-burning fireplaces, carved mantels, original moldings and refinished hardwood floors. Typical layouts include separate formal dining rooms, windowed kitchens with pantry or staff-room niches, small entry foyers and in-unit storage; some units offer private outdoor space or large planted terraces. Building amenities are full-service and resident-focused: 24-hour doorman, live-in superintendent, elevator access, on-site gym, laundry room, planted roof garden/roof deck, bike room and transferable private storage bins. Pied-à-terres and pets are permitted subject to co-op board approval, and partial financing (typically up to 50%) is allowed. The property sits on a quiet, tree-lined Upper East Side block within easy walking distance of Central Park, multiple subway lines, restaurants, shops and cultural institutions, offering a classic Manhattan lifestyle that blends historic character with modern conveniences.
