@Ben785 Nearly all of your reviews from the last few months have reported issues with the cleanliness and condition of your facilities. These are coming from guests who have been positively reviewed by other hosts, with no indication that they're serial con artists.
There are scammers out there for sure, and the sheer volume of negative reviews is likely scaring away the better guests. But the evidence overwhelmingly suggests that your property has not been delivered in the condition advertised for quite some time, and you have some very real problems to address there. Your responses to critical reviews often mention money and discounts, but the fact is that whether guests are paying $10 or $10,000 a night doesn't matter - the home still has to be clean and in the condition it's advertised to be.
