@Wendy684 I agree with @Branka-and-Silvia0 . Prospective guests can't see the individual ratings left by other guests, only the text of the public review.
And your rating is not "damaged." It was never going to stay perfect forever; no matter how hard you try to get everything right it's inevitable that some guests are going to be more critical than others, or less of an ideal fit for your listing. If you're going to be dealing with the public and exposed to feedback, you've got to keep a thick skin about it. Accept the great reviews as praise rather than an entitlement, and also accept the critical feedback as a chance to learn and improve. I realize that Airbnb is actively encouraging a neurotic attitude to ratings by making anything less than 5 stars feel like a failure, but that's just a manipulation tactic to make you feel subservient to the almighty algorithm. Don't take the bait; star ratings are not worth the emotional distress.
If you find yourself truly unable to cope with a mixed review, it could be that renting to strangers is not for you. That would be a shame, because it seems that you really enjoy it; I hope you find a way to take those stupid stars with a grain of salt and move on.
