How do review responses work?
Hosts and guests have 2 weeks to leave a public response to a review they've received, once the review is public. The response will appear directly below the review, on profiles and listing pages.
To leave a response, go to Edit Profile > Reviews and select the Reviews About You tab. For any reviews that you’ve received in the past 2 weeks, you’ll see a Leave Response link. Just be sure to Submit when you’ve finished writing your response.
