64 West 48th Street has undergone a multimillion-dollar capital improvement program. Located between Fifth and Sixth Avenues in Manhattan's Diamond District, and just off the heavily trafficked Rockefeller Center, this prime Midtown property now features a beautifully restored lobby, new elevator cabs, common areas and windows, an upgraded exterior and roof, HVAC system and electrical system upgrades, new restrooms, and upgraded security systems and keycard access.
