@Tere32 " Especially since guests with no issues tend to not write a review."
That may be your personal experience, but it's certainly not true for others. All my guests but 2 since I started hosting over 3 years ago has left a review, and none of them had "issues- they all left 5* reviews.
I'm not particularly surprised that your guests have "issues". I looked at your listing and reviews and while guests indicate that you and your family are sweet and nice, it sounds like you have tried to cram as many people into your place as possible, with little to no privacy. Guests consistently talk about the inaccuracy of the listing, how cluttered it is, and how dirty the bathroom is. If it was just a one-off review like this, I'd dismiss it, but so many of them say essentially the same thing, that I'm surprised you haven't addressed these issues or don't consider them to be of any importance. If you are going to run a hostel-type listing, why wouldn't you keep the shared bathroom clean? It's really unfair to the clean guests to make them put up with dirty guest's habits in shared spaces and equally unfair to not disclose the hostel-type situation.
