Hi @Joy912 When your guests check out, within 12 hours or so you'll receive an email from Airbnb inviting you to review your guests. They will also receive an email at the same time, inviting them to review their stay at your place. Both parties have 14 days to do so. If your guests submit their review first, you'll receive a email from Airbnb advising that this has happened, and saying that you will be able to see their review once you submit yours. And vice versa.
All the best.
