@Jin726 Yes, it happens sometimes, though not really often, I think. People can get confused about the review and the private comments.
Nothing you can do about it, once reviews are posted, nothing about them can be changed. Even if the guest asked Airbnb to, they won't.
Just be glad that although the public review was only a one-liner, it's great.
I once got a review that said nothing but "I spent the best week of my life here".
And another that, while it was a good review as far as it went, (and the guest had told me he was going to leave me a great review), the guest somehow screwed up and the review cut off in the middle of like the third sentence.
