The great prewar co-ops of the Upper West Side represent Manhattan residential life at its most civilized, and this four-bedroom is a prime example: a grand gallery entrance, library with custom built-ins, formal dining room for twelve, and a kitchen rebuilt to support serious entertaining. At 2,800 sqft, the apartment offers room proportions that simply cannot be replicated in modern construction. Building is an extremely well-run white-glove co-op with reserves in exceptional health.
