The Residences at the Ritz Carlton at 50 Central Park South are on the top 12 floors of the 33-story Ritz-Carlton Hotel building on the southeast corner at the Avenue of the Americas.

There are 11 very large condominium apartments on those floors and 259 hotel rooms beneath them in the building that was originally the St. Moritz Hotel designed by Emery Roth in 1930.

The 2002 conversion of the St. Moritz into the Ritz Carlton and the creation of the Residences were by Millennium Partners, of which Christopher Jeffries was a partner.

In 2008, Mr. Jeffries sold one of his apartments in the building for $28 million and in March, 2012 he put a duplex apartment on the 30th and 31st floors, that he had purchased in 2002 for $20 million, on the market for $77.5 million.  Part of the apartment was the hotel’s former ballroom, which boasts 15-foot-high ceilings and spectacular views of Central Park.
