When I rent my flat out to Airbnb guests, it is with a lot of trust, because it is my apartment, I live there, so, yes, my personal stuff is there. It is mentioned pretty clearly, especially when I say that my kid's room and my mezzanine bed are private spaces. If you expect an emty hotel-apartment, then there are other solutions for you than airbnb.
About my neighbor not speaking english, she told me she tried her best to explain everything to you but as you didn't speak any word of english, it wasn't easy.
I was travelling myself so, I didn't come back, but my kid forgot a schoolbook, so yes, as an innocent child she just passed by "home" to pick it in her room.
I also wrote you several times from abroad to check if everything was ok and you never complained or said anything. I feel betrayed by your behavior and regret strongly that I have let you enter my place.
I won't recommend you as a guest.
