You can email her and request that she write a review, because the time to do that is going to end in another 4 days. I find that if I ask for guests to review my place on their last day, they usually comply, so I've never had to follow through with them. it's not fun to lose what you believe would have been a good review.
If you write a review for her, she will know in a message from Airbnb that you have done so and they will prompt her to review you so she can see what you wrote before the 14 days elapse. Throught that means, you are able to send her a private message, that is not seen by anyone else. In that message you might schmooze a little and tell her that you would appreciate her review based on her thorough enjoyment of her stay.
