Hello @Allan-C-0,
Within a day of checking out a guest should receive a notification on their Airbnb account and an email prompting them to write a review. If they don't write one they should receive a reminder giving the remaining time period they have to write one.
Neither side can see the other's review until both have written one or, if only one side writes a review, until after the 14 day review window has passed. That is, if only one party writes a review that review will appear on the other's profile after 14 days.
If you write a review you can edit it within 48 hours or until the other party writes one, whichever is sooner.
Some guests don't write a review even when also reminded by the host. It's particularly frustrating when a host is starting out and is eager to build a reputation by getting good reviews.
Steve.
