Curbed reports that dental clinic owner Alexander Mikhailov, an original apartment owner at Fifteen Central Park West, has put his 34th floor unit (shown) up for rent. One of the building’s center apartments (described in House of Outrageous Fortune as a railroad flat for rich people), it is being brokered by realty firm Mercedes/Berk, whose principals are not only business and life partners, but also Fifteen residents, and Noel Berk holds a seat on the posh condo’s governing board, which likely won’t make the approval process for the $55,000-a-month rental easier, but certainly won’t hurt any applicants’ chances.
