The place was really nice and super well located. Clean and big with everything you need in. I personally didn't like Palermo, but the area I liked the most (and the best restaurant of town is in front of the flat "bisso") is near the flat.
Ivan was very attentive and made sure to be always quick at replying. He even helped us with our luggage being kept later than our Check out and helped us with cab etc. All in all of you go to Palermo, go to his house!
