@Amanda1389 Unfortunately, you don't have a viable argument here for several reasons:
1. It appears that you didn't submit a review for the guest. This effectively negates your argument in the Host Response that she "left your property in a bad state." Everyone is aware that dishonest retaliatory reviews exist, but when something goes wrong and only one party writes a review, it really looks like the other party is the one at fault. Is she was such a bad guest, why didn't you review her to alert other hosts?
2. You claim that the guest is lying about bedrooms not having curtains. Well, look at the photos in your listing. They show several bedroom windows that don't have curtains. Maybe you've just forgotten to update your photos, but until you do that it's hard to make the case that the guest was dishonest.
3. We all have different ideas about which utensils are essential to a fully stocked kitchen, but if your guest felt that your supplies weren't adequate, that is a subjective but relevant comment. It's not a good look when you call the guest a liar rather than seek feedback about how to improve the kitchen supply.
One of the worst things about Airbnb's "5 star default" culture is that hosts are instantly put into the defensive posture when a guest rates them anything less. The most common reaction is "all my other guests rated me 5 stars, so therefore I am perfect and you are dishonest." You appear to be a very new host, with a listing going back only 4 months, so it's only natural that there are still some things about your very nice listing that could use some improvement in the eyes of some guests. As hard as it is to get negative feedback, I recommend trying to learn from it and move on rather than shooting the messenger.
