I too found this so confusing. On the app, when the guest sends a request to book, you will have a message from them. Open the message. At the top of the message There is a link to your listing and right next to the link, is a very squished red vertical oblong thing. Click that. It will not show you their picture, but it shows their reviews and profile and how long they have been a member. On the website, it's much easier and more clear as when you open their message or pending request, their info is just to the right of their message once you open it. Hope that helps. It took me a looooong time to figure that out on the app. Being a single mom who is renting a room in my home I always check reviews before allowing anyone to book with us. Knowing how to find this has been invaluable. Hope this helps!
