@Raymond-and-Elaine0 It is a common sense that none of us can stop a small number of guests from bsing and there's really nothing we can do about it. That's the nature of this business. Always bear this in mind, that if you have more than 100 5-star reviews on your profile, nobody is going to give a xxxx about the couple bad reviews. It's not going to harm us at all. Everyone with reasonable judgement can tell that if there are >100 5-stars and a couple of 1 star, those posting 1-star reviews are most likely lying or nit-picking. And in most cases, the bad review you give to the guest will do much more harm to them than the bad review from the guest will do to you. Just move on.
This happens in hotel industry as well. I remember years ago when I did road trips often, I usually booked motels and inns on websites like priceline or hotels.com. When I look at the reviews of those hotels, even a lot of 5-star luxury ones can hardly reach 4.5/5 stars rating, while most motels and inns are rated anywhere from 2 to 4 stars. After some trial I found the fact that a >3.5 star rating means the service is very good, while >3 is at least acceptable level. Even some rated 2-3 stars are not bad as well.
