A no-show, non-communicating, cancelled-days-later, refund-wanting guest once wrote a revenge review here, but since all my attempts to reach out, and all her silences until her threats started were in the messaging system, Airbnb took the review down, @Asım0. She had not set foot on the property, so it made no sense that she could rate cleanliness, check-in, location, or even value. Maybe communication, but the system is not set up for one parameter. Is your conversation with the guest in the messaging system? If you are notified that the guest has written a review, call or tweet Airbnb and ask to have it taken down, since, no matter how many stars, it cannot possibly reflect the guest's experience.
