The Waldorf Astoria New York is a luxury hotel and condominium residence in Midtown Manhattan in New York City. The structure, at 301 Park Avenue between 49th and 50th Streets, is a 47-story 625 ft (191 m) Art Deco landmark designed by architects Schultze and Weaver and completed in 1931. The building was the world's tallest hotel until 1957, when it was surpassed by Moscow's Hotel Ukraina. An icon of glamor and luxury, the Waldorf Astoria is one of the world's most prestigious and best-known hotels. Waldorf Astoria Hotels & Resorts was a division of Hilton Hotels, and a portfolio of high-end properties around the world operates under the name, including in New York City. Both the exterior and the interior of the Waldorf Astoria are designated by the New York City Landmarks Preservation Commission as official landmarks.
