There was an entrance hidden behind her bathroom mirror.
A mysterious draft is what tipped her off - she felt cold air blowing on her, and the air was coming from the mirror.
Hartsoe made a four-part series on her TikTok about finding the apartment.

It is unclear whether building management knew about the space.
