@Jeanette37 personally I would never have people staying inside my home. But to ur question...it is invasion of privacy and makes no sense that u have stuff in a room for guest and enter during their stay.. It should be emptied except for what is for guest. If u can't do that... maybe rethink hosting.
Many of us here read listings n reviews n it would be really good if you realize the image you are putting out there as a host. You are obviously responding to some private comments that guest wrote you and you are responding publically and making your responses so strong, defensive and sometimes pretty ugly. And you rant on and on. I just wondered if you realize that this is surely not helpful for future bookings. Several others had good suggestions. Keep your cool, it will serve you well.
