@Eddie-and-Kris0 This review is so unhinged and so obviously an outlier that no prospective guests will take it seriously. Calling you racist, when you are obviously a mixed race couple, should be grounds for getting it taken down. But I wouldn't waste a whole lot of time or stress on it.
I do agree with Colleen that you should ask for your response to be removed.
Responses appear on your review page, not the guest's and should only be used to briefly correct misinformation or lies for the benefit of future guests, who couldn't care less about the behavior of your past guests.
The response to this review should have been something like "This is a revenge review left due to this guest not reading the listing information, being called out for her rude and entitled behavior, and being requested to pay for the extensive damage she caused and the huge mess she left behind. The accusations of racism are ludicrous- we are a mixed race couple and all are welcome here who show respect."
Your review of her is also far too long. I realize you were angry, but all other hosts need to know is general info, not all the gritty details. " Worst guest ever. Failed to read the listing info and house rules, violated house rules and instructions multiple times, no communication about arrival time, despite a clear request that this was required, caused multiple damages and left the home in an unbelievably filthy state."
People tend not to read through lengthy reviews and responses, which defeats the purpose of leaving them. It's always best to wait until your initial anger has dissipated before writing a review or response for a terrible guest.
