@Bruno1316 , I had one guest that I gave a poor rating (3 star) but didn’t say anything in my written review. I just left a “.” There wasn’t anything horrible about the guest but I really didn’t have anything positive to say. I did mark the button that I would not recommend to other host(s).
If there is no written review, does it show the host(s) that left the 3 star rating. If it does show the host, I would reach out to the host(s) and inquire why the 3 star etc… If the rating does not show a host(s) information etc…I guess you’ll need to rely on your gut instinct.
Best—
