Contact with Laura was very easy and she provided us with all the information to get to her apartment from the airport. We took the shuttle bus from the airport to Palermo's central train and bus station, her apartment is a four minute walk from the last stop, very easy to reach.
Her friend Davide was waiting for us in the front door of the building and checked us in. Our luggage was lost on the way to Palermo and Davide lent my husband a pair of polo shirts, which was very kind. We didn't get to meet Laura in person, but we were in contact with her during the three days of our stay in Palermo as she was helping us with communication with the airline to try to find our luggage. She exchanged messages in a daily basis with the airline and transmitted the information to us, which was very kind and certainly beyond her obligations as an Airbnb guest.
A word about Palermo and Sicilia: it's fantastic! The people, food, churchs, cities, we had a great time and would love to come back. To all of you who are making up your minds about going to Sicilia, our advice: go.
