My game crashed so I try to answer before I look again.
From what I remember the first room you can find is a suply closet or how it's called in english with a broken statue and stuff I think you found that okay.
Uhh Not sure if it'S needed but I remember the
telescope scene in the second floor and then two rooms left I believe Emily in the bathroom and to the right where your supposed to go. II have to see if I still have the save but I feel like doing that somehow has you end up on the couch with her. I try it later now I'm curious what's happening with the text here
