Sandra - here's a little more depth on the review process and what you might be anticipating -
Yes, even though only the guest leaves a review within the 14 days it will be posted on your account...... So make sure you write a review for the guest. When both are received, then Airbnb will make them public and you will be able to read what your guest has written, along with the stars. Then you have a chance to make a response - which will be shown/posted directly under his review on your profile. And he cannot write anything else.
So - two chances for you to make your opinions known.
Firstly - your review on him - be brief, polite but accurate - something like..... you were disappointed he didn't complete his booking due to his last minute change in dates but you hoped he enjoyed his stay. And don't be afraid to give him a thumbs down.
Secondly - your response to his review on you - take a deep breath after you read whatever he wrote - and don't take it personally. Reply in a way that shows you to be the professional, genuine and cool host you are - mention that you appreciate his comments and you are sorry he wasn't happy but you tried hard to make his stay pleasant and you wish him well.
Overall, this potentially one 'bad' review won't make a difference and it certainly won't make future guests book elsewhere. Really. So don't let it affect you and don't be tempted to respond in a defensive or snippy way - take the high road and live to host another day (while you have his money in your bank account! 🙂
Best of Luck,
