@Chui-Ling0 This is a good lesson for you and other hosts. You write its a private room and bathroom in your home and the guest will have exclusive full use of guestroom and bathroom. Well, maybe you aren't a curious person but almost all people I know would be looking around and if you left a bunch of stuff, seems only sensible they would look.....good thing they didn't take whatever they liked. So its not wise to leave things that you don't intend to share with the guest. Even some hosts have locked rooms and those very curious, overly criminal type will bust the lock and get in there to "see what's so valuable". I've seen video footage of that very thing. So put away your things and secure anything you treasure or be willing to lose it. I do hope you are not really gonna report them....they didn't really make the big mistake...sorry, you did. You said they did Not steal anything. That would be a different story, but still it would be some big fault on your part. Hope this makes sense. This behavior is called curiosity, exploration and for many normal to look and see. My opinion. happy hosting
