Building
Conceived as a walk-to-work boutique office building at the Northern edge, 667 Madison was built to meet a specific set of needs desired by family offices, alternative asset management businesses, and boutique office occupiers.
With ownership by Leonard Stern and son Edward, they pride themselves in operating New York City’s finest boutique office building, providing first-class service that is unmatched in the Manhattan marketplace.

Building
Located on the northeast corner of 61st Street and Madison Avenue, 667 Madison sits at the intersection of two of the city’s most prominent neighborhoods and is one block from Central Park. The asset’s location is unique in that the area’s traffic and streetscape feel more like a residential neighborhood rather than a hectic commercial district. The city’s most important shops, restaurants, cultural experiences, and hotels are within walking distance.
Amenities
Modern Systems
667 Madison’s elevators, cooling tower, air handling systems, air purifying systems, and internal fiber network have all been recently upgraded, and ownership is committed to maintaining the building’s systems to the highest possible standard.
Private Elevator Service
Elevators have been pre-programmed to accommodate “express rides” from any floor directly to the lobby, and lobby attendants can arrange private car service to any floor in the building upon request.
