@Julie4489 Did you get paid for that booking? I wonder why their booking was cancelled. And I also wonder why they left a brief but nice written review but 1*. Seems odd.
Well, the good review you left them is a moot point now, because they no longer have an account.
But you should never think that if you left an honest review, that was a bad thing, just because the guests didn't leave a good rating.
Reviews are meant to be an honest reflection of your experience of the guest, not a tit for tat, you leave me a good review and I'll leave you a good review. If the guests left the place clean, didn't break any rules and communicated well, then they deserve a good review.
I have read of cases where a guest left a 1* review and when the host questioned them about it, as there seemed to be no issues during the stay, the guest said they thought 1* was the highest rating!
