This is a handsome 21-story neo-Georgian building designed by the architect George Pelham in 1929-1930. This very prestigious Park Avenue co-op has doormen and a Fitness Center. Its entrance is quietly positioned on 90th Street and the original architect designed the building in a wedding-cake style to showcase the center section and upper floors. It is conveniently located to the subways, schools and two blocks from a main entrance on Central Park as well as the Guggenheim Museum and Cooper Hewitt Museum.
