When I read the reviews and saw the complaints, I gave the listing/host the benefit of the doubt thinking some people just like to complain... especially because there was a defensive response that left each reviewer in a negative light.
I wish I paid attention to the aggressive responses to those complaints/concerns, because when I had a problem (first one in using airbnb for over a decade) I was met with very unhelpful aggression & greed. I had to get Airbnb involved as she was not responding.
Instead of going into all the details, I will simply note the pattern.... and watch the negative comments surely as a response to my review.
I wish you all lovely trips in Sicily.
Read the reviews.
I had a sewer smell problem that got progressively worse each day.
