>I don't airBnB, but a friend who does was recently berated by a host after leaving a 4-star review; that host claimed (don't know how true this is) that many hosts will refuse to rent to you again if you leave anything but a 5-star review. Airbnb pushes hosts really, really hard to achieve >80% 5-star reviews. If <80% then the listing gets pushed down the rankings and you lose SuperHost status. Some guests never give 5-star reviews for whatever reason. They really, seriously hurt the host. If your average is >4.0 (and it should be over 4.5) then any review less than 5 stars will lower your rating. I worked in a restaurant and was trying hard to get our TripAdvisor ranking higher. One quiet night a guy comes in so we chat and give him some great service, special dishes etc. At the end of the meal he said it was excellent and had left us a 4 star review. I said "Dude, our average is 4.8 stars, you just made us look worse." In the end we got to #2 in our city. The #1 was a cafe that was only open 7 am to 4 pm. All you need for 5 star review in a cafe is a hot coffee, so we settled for #2.
