23 Park Ave

A landmark five-story Italian Renaissance–style palazzo converted into an intimate cooperative, this 1898 masonry mansion contains thirteen apartments primarily configured as two-bedroom duplexes. Externally the façade preserves historic ornament: tall, arched windows, carved stone detailing and a formal stoop that align with the landmarked streetscape of Murray Hill and Park Avenue. Interiors vary by residence but commonly retain prewar character—high ceilings, original plaster moldings, wood-burning fireplaces, built-in millwork and expansive window openings—alongside contemporary upgrades such as renovated kitchens, marble baths, multi-zone HVAC and integrated sound systems in select homes. Common areas are modest and service-oriented: a staffed superintendent during daytime hours, elevator access, shared laundry facilities and limited private outdoor spaces including small terraces or garden-level patios. The building permits pets and has limited storage; parking is not a principal on-site feature. Located where Murray Hill, NoMad and Midtown converge, it offers immediate access to Grand Central, transit lines, cultural institutions and a dense mix of restaurants and services, delivering a residential experience that blends preserved Gilded Age architecture with modern apartment living.
