Hello @Cindy84,
As she's already left a review it will appear on your profile and listing page when you write one of her. If you don't write a review her review will appear on your pages anyway after 14 days.
Hosts can edit a review within a certain time after writing, maybe 48 hours, or until the guest writes theirs.
I presume that the same applies to guests. In any case, once you write your review the guest cannot change theirs. They can write a reply which appears only on their profile page just like you can write a reply to their review and it appears only on your pages.
As she's already written her review she can't retaliate after seeing yours.
You can leave a review to say whether she was tidy or not, arrived on time or not etc. and saying something neutral like "X would be better suited to an hotel environment". You then decide how to rank her on communication, cleanliness and observance of house rules and whether you say yes or no to recommending her to other hosts.
Steve.
