@Eileen462 Both guest and host have 14 days post stay to review each other. As soon as both parties have reviewed the reviews are posted. If only one party reviews then their review is posted after 14 days and the other party cannot review.
Other things to note:
At any time you can ask for YOUR review to be deleted
At no time can you edit/correct a published review (you can edit an unpublished one for a short period of time)
You can respond to a review but cannot then get this response edited or deleted
Responding to a private comment left by a reviewer becomes public (weird I know)
