although its most likely too late now as You have sent a deposit. but in the future, use airbnb, all deposits go through airbnb. owners do not get anything until you check in.
if there is a problem, either the host remedies it immediately or airbnb will handle it. I stayed in an airbnb in sint maartin and it was not like the pics. I let the owner know immediately and their response was "we were in a rush today to get the villa ready for you", sorry things were not up to the pics. I told them I will stay but requested a 200 dollar refund which I thought was fair. it was a 4 day stay. the owner refused and said she would give me a discount the next trip. I told her there would be no next trip.
since it was too late by the time I arrived to change. I let airbnb know the situation with pics. airbnb sided with me and gave me the $200 refund. I normally always give a 5 star rating as this was the only time in 11 years of using airbnb that I was disappointed and the owners before had always been helpful if I had a problem, after checking out of the sxm rental, I did the review and gave a one star as I felt I had to waste my time to get the refund requested, I would even have accepted a lower amount from the owner but she stood firm and said she never gives refunds.
