108 E 91St St

A boutique prewar cooperative on Carnegie Hill, this nine-story Neo-Renaissance building was completed in the 1920s and contains roughly two dozen to three dozen primarily one-bedroom residences. Characteristic prewar details—high beamed ceilings, parquet and wide-plank hardwood floors, decorative fireplaces, original moldings and glass doorknobs with brass hardware—are common across units, many of which have been selectively renovated to add contemporary kitchens and bathrooms while retaining period charm. Common areas include a modest lobby with part-time doorman coverage, a live-in superintendent, passenger and service elevators, a newly renovated laundry room and communal bike and storage facilities; some listings reference a shared garden or patio and deeded cellar storage. Building services and policies are purchaser-friendly: pets and pied-à-terre ownership are typically permitted, sublets and guarantors are allowed with board approval, and financing is commonly permitted up to current co-op thresholds. The structure sits on a tree-lined townhouse block moments from Park Avenue, two blocks from Central Park and the Museum Mile, with convenient access to the 4/5/6 and nearby subway lines, neighborhood institutions such as the 92nd Street Y, and local markets and boutiques, creating a quiet, residential urban environment with strong cultural and recreational walkability.
