At the time of sale, the Faena Duplex Penthouse was the most expensive single family home deal ever brokered in the Miami area. 

From the Miami Herald:

The Faena House penthouse has nine bathrooms, a 70-foot-long rooftop pool and a wrap-around terrace with views of the Atlantic Ocean, Indian Creek and the downtown Miami skyline. The 42-unit building also offers all the amenities ultra-rich buyers demand in Miami: an in-house spa and fitness center, a private club, concierge service and a round-the-clock doorman. It was originally listed for $50 million.
