The star-rating system used by both hosts and guests is intended to rate the descriptions and expectations for them being met, not some golden luxury paradigm. Many hosts have older properties, humble but certainly habitable. These are even preferred by some over the boring sterility of commercial hotels. Guests have hurt many hosts and provided no usable information by giving 1-star reviews in every category, sometimes putting a host out of business. A current display of average ratings GIVEN BY a guest would be a great indicator for a potential host to evaluate their risk. It is fair and self-regulating. A guest abusing the system will be turned away more often and quickly realize they must be fair and honest too. There is a third party app out there that does this but it can only search for the hosts that received reviews from their hosts. These are rare because the host may not really have anything useful to say about someone they never met who came and went and didn't cause problems. We hosts would like to see an average star rating GIVEN BY the prospective guest prior to booking. Airbnb has taken steps to avoid discrimination but this is different and we need to see it before approving their request.
