@Kathryn570 Why do you not want to leave a written review? (No, you can't just rate and not leave a review).
First of all, hosts who do not use Instant Book cannot see guests' star ratings. We have only the written reviews to go on.
Secondly, star ratings are entirely subjective and give no explanation of why that rating was given. What might be a 3* guest to you might be a 5* guest to me. Different hosts have differentt expectations of guests, so may rate quite differently.
If everyone only writes reviews that are glowingly positive, and doesn't leave honest reviews for all guests, even if they weren't good guests you would welcome back, the review system is pointless.
Please leave an honest written review. If there are good things you can say about the guest, include that along with the negative. Example:
"Pre-arrival communication with xx was good and they followed house rules. Unfortunately, hair dye was found on towels and staining the shower stall and kitchen was left quite dirty."
