Davide (Simona's husband) came to pick us up in the central square of Catania. He took us to the apartment, helped with the parking and gave us many useful suggestions. We definitely felt welcome.
The apartment was not the one in the picture of Airbnb (Davide explained there was a last-minute issue with that one), but the flat where we stayed was definitely an upgrade (bigger and more centrally located). This flat is in a beautiful central building and it's big and classy. The kitchen as well as the bathroom had all the needed items for a pleasant stay (breakfast basics, towels, soap, shampoo, hairdryer etc. - we appreciated the extra bottles of water very much!). Unfortunately on the third day of stay there was a problem with the pipes of the building and when we came home at night after an excursion we found there was no water for showering or so. We called Simona and Davide, who were aware of the issue already but were not sure if our flat was affected as well. They provided us with the keys of a flat in the same building where water was available in order for us to shower. This flat was in construction so we had to adapt a bit to the unfortunate circumstances but overall it worked out fine for us. Water came back the morning after.
