My room is on the 9th floor, Room 906.
Around 5:10 PM, someone knocked on the door to deliver towels. What I didn't like, and I don't think it should be done, is that after knocking 2-3 times, he immediately opened the door himself. (He used his own access card.)
My wife and children were scared, as he was already quite old. You can check the CCTV if you want a clearer picture.
