We received an email in Italian (all other communication was in English) from the host the morning of our 10 am departure, informing us that we were responsible for paying a plumbing bill (250E) in full because our toilet backed up one week before we departed. We only used toilet paper and we are in our 70s and know how to properly use a toilet. This was extremely upsetting and it required a lot of time to figure out her Italian and then to respond to Airbnb so they would not charge us. To us, it was an underhanded attempt to charge us for something that we were not responsible for.
