It's sad to hear that you didn't enjoy your stay overall and I'm surprised that you found the pictures from the listing not to represent the room as our pictures are recent and are from the actual room, taken from different angles to give a good understanding of how the place looks.
After you informed us about potential scabies, as we already told you that it's sad to hear about your health condition and took action to investigate with advanced equipment and found nothing. We sought medical information for this and found out that symptoms take as long as 4-6 weeks to begin. While you reported about this to us only 2 days after your check-in, it seems that most likely you didn't caught up scabies from our place.
It's worth mentioning that you requested refund for this through the Airbnb Support and after you provided them with documentation they considered it not valid that's why refund was not issued. Nevertheless, thank you for your feedback overall and I hope you get better!
