Karol's room is on the bottom floor.. When she goes up the stairs it leads to the living room and a bathroom without a camera, which is where she disappears to., Roxy and Asty's room is also on the living room level. Looking at cam 1.7, the bathroom is just past the double doors. If you pass the doors instead of going through them, that leads to Roxy's bedroom. Because Roxy and Asty are close to that bathroom, you dont see much of their activites unless they shower. if you go up the stairs on 1,7 the first landing is the kitchen, the next set of stairs leads to the twins room. There's no roof deck
