In this case, @Sofia166, you might write to the guest and ask whether she meant another place, since she had said check-in was easy when she was talking with you just after the fact. You could refer her to that message. She might agree to phone Airbnb and ask to change it. Not sure, first of all, whether that will work, and also not sure she will be keen after your review mentions her messiness.
Or you could reply to the review with something like, "The guest had us mixed up with another accommodation. Her check-in here was smooth, as per her message at the time." That may be the less stressful route.
