The hotel building contains a facade of brick, limestone, and architectural terracotta. It contains light courts facing north and west, as well as setbacks to comply with the 1916 Zoning Resolution. The limestone base is two to three stories high and contains storefronts, a main entrance on 48th Street, and an archway on Lexington Avenue. The upper stories are generally clad with plain brick and contain random projecting groups of bricks; there is a narrow tower at the top of the building. The basement contains a restaurant space that formerly housed event venues, including the Hawaiian Room. When the hotel opened, it had 814 guestrooms, though this has been reduced over the years.
