Hello @Marty32,
Sometime during the day of her checkout you'll be prompted to review her. She will also be prompted to review you. If you leave a review of her first then she'll get a notification of that saying that she can see the review now if she also leaves one.
I don't know if guests get another prompt near the end of the 14 days.
If she hasn't written a review by day 11 or 12 you could consider sending a gentle reminder along the lines of
Hello XXXXX. Thank you very much for your reservation. It was a pleasure to have you stay. The Airbnb system works best when hosts and guests review each other so would be great if you could find a few minutes to leave one.
Steve
