Some of my guests went to several Airbnb right before coming to my place. They told me they were not satisfied of their previous Airbnb but they ended up not giving them reviews and gave me a 4 star. From their perspective, they think 4 star is good. But I feel that I should have given them a lower quality Airbnb such that they don't leave me a review rather than give me a 4 star. A 4 star would actually lower my rating and my future guests will see a 4.5 star if I have many 4 stars. I wish that Airbnb would give penalties to the overall ratings even if guests don't leave a review
