First of all I'll recommend for everybody. It was our first time in airbnb. Place was great, we had no problem with getting there and we had warm welcome with some tips and informations about place, neighborhood and city itself. There were everything we need, separate kitchen with dinner, bathroom and bedroom with huge wardrobe and queen bed. As for breakfast it's typical Sicilian one so croissants (with and without stuffing) and coffee machine with coffee (we had also some additional things like milk, juice and so on).
We were in contact with our host in case of any questions and it was very smooth. Apartament is located around 10-15 minutes walk from city center, there is bus stop near for longer trips. Also there is an air conditioner inside bedroom and works as expected. So summarizing if you are looking for clean, pleasant place, near city center with no problems you should book it :)
