@Helen56 I strongly disagree with you. I'm currently staying for a month at a house, and my host has entered my room at least three times -- without prior notice -- to open a window because the house was getting stuffy from warm temperatures, get something out of the closet, etc. She did not enter because I broke house rules, such as leave the lights on. The third time, she entered it and moved half of my belongings around to her liking, even my underwear and laptop. Incredibly creepy and inappropriate. She claimed it was because she was making sure my stuff was protected from the moth fumigation, but 1) she had notified me of the fumigation the previous week, so I had already covered/packed anything necessary, and 2) it was the type of fumigation that doesn't leave harmful residue. From my perspective, she used the fumigation as an excuse to root around. It took me an hour to find everything and sort it all back to my organization system.
And no, I am not messy, and I don't stink -- previous hosts have noted how neat and clean I am. Even if I were messy, I can be messy in the room I rented as long as I'm not damaging anything or leaving food to rot for days on end, then leave it clean at the end of the stay.
I was irate and sent a strongly worded message to her on the Airbnb messaging system to have it properly recorded. If she enters the room again, I will file a formal complaint to Airbnb. I did not pay $3,000 to have my belongings touched by a stranger, and my private space freely invaded.
So, sure, it's your house, and you have the right to feel like you can break the privacy rights of guests who have paid you good money. But guests have the right to make a much stronger claim of invasion of privacy and inappropriateness, and report you. Be prepared to deal with the consequences of poor hosting etiquette.
