Though Madge purchased a single unit back in the mid 1980s, over the years she's bought two more neighbouring apartments in the building, combining them into what is now a 6-bedroom, 8-bathroom duplex, which takes up the 5th and 6th floors of West 64th Street's prestigious Harperley Hall, according to real estate website Zillow.

The apartment was featured in a 1991 issue of Architectural Digest, and according to the article, Madonna's brother Christopher Ciccone (who later turned on her, writing a tell-all book about his sister) served as her interior designer. Ciccone stocked the kitchen with high-end stainless steel appliances, kept a set of original (circa 1915) leaded-glass doors that lead to the living room, and sound-proofed the private gym so that neighbours couldn't hear the stereo system. "Madonna likes to feel the music," Ciccone told the magazine at the time.
