Amazon CEO Jeff Bezos just bought the makings of an $80 million mega-residence in New York City. But before the richest man in the world purchased the three-level penthouse at 212 Fifth Avenue, plus two additional apartments, CNBC got a tour of the triplex with Sotheby's International Realty broker Nikki Field.

The sprawling 10,000-square-foot penthouse has five bedrooms, five-and-a-half bathrooms and a seven-room master suite.

"[The master suite] is a dream," Field told CNBC in October 2018. "There's a private bedroom, as well as two dressing rooms, two extraordinarily well-outfitted bathrooms, a sitting room, and a home office, numerous closets, magnificent views and privacy from the rest of the home." Inside the master bathroom is a breathtaking view of the Empire State Building from the tub.

In addition to the master suite, the first level of the main residence also has a great room that connects to the home's kitchen and formal dining room.
