Pretty much the core of the STR business.Higher your rank gets, you can increase your price and be more picky in selecting customers which usually lead to a better review / less party or complaints / less expense and higher profit with a happy life.I know some people will argue, but the ranking system is the truth and should be the only guide to your STR journey.
