On the 33rd floor, Melania owns apartment H. There aren't any photos of that unit available online, but these photos from StreetEasy show apartment 32H, which looks to have the same layout as hers.

It has one bedroom, also with sweeping views. Trump's disclosure form lists "721 33H LLC", the address to the apartment, and a pass-through company for the property, saying the real estate is valued between $1,000,001 and $5 million.

It also has a sizable walk-in closet, though Melania's closet in the penthouse upstairs is much larger.

In January 2016, Melania bought the unit for $1.49 million, apparently from the building's condo board. It appears to be the only unit the condo board has ever bought, according to property records The Real Deal obtained.

This type of unit (a studio or one-bedroom in a luxury skyscraper) is usually used used for staff of residents who have much larger apartments in the building, or for a live-in building superintendent. The condo board first bought unit 33H for $650,000 in 1997.

While it's unclear why the first lady bought this apartment, some speculate she bought it to use as a library. Maybe it's just a private space for her to get away from it all and relax in private — since Melania's never mentioned the apartment, it's a mystery.
