Isadora, whose real name is something else, was to move from Stockholm to Örebro to study at the university, and that was when she found the man's advertisement.
She says that the accommodation felt safe, but then suddenly cameras began to appear in the apartment.
Looking in the room
Isadora told a friend who thought she should look for cameras in her room too.
But the only thing that was there when she moved in was a mirror.
She tried to remove it, but the mirror was firmly screwed into the wall.
At the same time, Isadora noticed that there was also a box behind it.
- I thought this is very scary, she says.
When she finally got rid of the mirror and the drawer, a camera and a microphone fell down.
Isadora called the police.
The apartment was blocked off and soon they found another camera - hidden in a basket in the bathroom.
Filmed naked
Material on several young women was stored on a hard drive.
The women had been filmed when they were naked and in some cases when they had sex.
The police also found a large amount of child pornographic material.
Hear Isadora tell in the clip above what happened next and what she thinks about the verdict.
SVT Nyheter Örebro has also been in contact with the councilor who ruled in the case, but he does not want to comment.
