@Alice506 I'm not sure if you can see those responses, but I could be wrong.
It used to be that you could maybe figure it out if a guest had six reviews, for example, but their profile said only four hosts recommened them. That begs the question of why the remaining two reviewing hosts did not. I am not sure if you can see this anymore.
If you use Instant Book, you can see the star ratings the guest has been given by a previous host, which should give you some idea. It is unlikely that a host has given a thumbs down and then five stars overall. Also, with Instant Book, you have the option to only allow guests to use it for your place if they are recommended by other hosts. I believe that means if they have a thumbs down/not recommened, they would not be able to do so.
If you are not using IB, I'm afraid the ratings are totally hidden and you can only go by the written reviews.
