@Marielbys0 I had experienced a similar issue when I made my first claim at one of my properties. I don't know why/how it happened, but the guest had tipped over a can/container of motor oil onto the carpet in their bedroom, tracked it everywhere, and failed to say anything till check out, so the smell permeated other areas. The evidence was overwhelming and like your case, was documented with multiple clear photos, yet they fought me tooth and nail.
I wish I had a more concrete answer for you, but I just stayed on them. I called daily, sometimes more than once, I requested different case managers and I called their cooperate line (855) 424-7262. I have also heard reaching out to them publicly on platforms such as twitter gets a faster more efficient response. The inherent issue is that all their ambassadors are usually working in call centers somewhere and know nothing about Airbnb. They simply read off prompters so to speak.
On a side note, your photo looked familiar and I realized I have your property Eden hill saved in Exuma. I plan to book it when I travel there in a few months.
Hope you are able to resolve this issue
