Stayed in a house booked through booking.com the house was dirty, garden overgrown etc. We were away for family funeral so just made do, the host is now saying we blocked the toilet with toilet wipes (we definitely didn't flush any down there) they told me the toilet easily blocks so obviously a regular occurance. They are also saying we left rubbish everywhere, we emptied the bins and left the recycling nicely by the bin as there was no recycling bins available. They are now demanding money, what happens if I don't pay? As I shouldn't as we didn't cause any damage thanks
