If you want to see if the guest has any other reviews, you can click on their profile photo and it will take you to their profile. If they have stayed at an Airbnb and been reviewed, the review will show on the right (you may need to scroll down) and there will also be a review badge (see image below) with a number inside it representing how many reviews the guest has had. I have not had a lot of guests with prior reviews so screening the guest is very important.
