When reviewing my guests in the category of how clean they left the space, I give about 98% of my guests a 5 on a scale of 1-5 (Airbnb's 5 rating being the best). It pains me to give most everyone a 5 though when they really aren't equal at all to how they left the space. There are those that go above and beyond, doing extra duties that I did not put on the check out list. In general, these are the type of guests who are more conscientious than most others and it sucks that there isn't a rating that reflects and/or "rewards" these efforts. Just the same, I realize that "going the extra mile", should not be the criteria for getting a 5 rating in this category. I feel that all those that leave space in a reasonably clean manner deserve no less than a 5. Is it possible to have maybe a 5+ or a 5 with a star next to it indicating an "above & beyond" 5 rating? Or something in this regard?
