Hello @Kelly535 ,
I have 5 listings, all of them doing well related to reviews and "stars". But all of them Airbnb says "i have to work on them", which is only the acceptance rating. My "superhost" status recently was taken away just because of this (but you know what: i felt relieved ! )
I came at a point to ignore those stupid rating and warnings. By being very serious about acceptance (same as you mention above), i think i save myself (and Airbnb) a lot of trouble. Airbnb is not running my place, it's me ! And i receive guests also via other channels, including directly via private website.
So Airbnb: stop treating mature and experienced hosts as if they are snotty childs. Thank you.
