Sorry to hear about your experience @Lina6924
i am wondering why if you saw previous negative reviews about the property you decided to book?
if you followed the process on your booking confirmation and raised concerns with the host first and the host didn't respond or couldn't address then you can ask airbnb to intervene. What did the host say when you raised these issues with them?
obviously you can't ask for a full refund once you've stayed for the duration
as you have photographic evidence and presuming you followed the process for raising guest complaints upon providing evidence Airbnb will consider a partial refund.
