I had a perfect stay at Lina's place! First I missed my flight to Catania and came one day late, Lina was so kind to extend my stay for one night for free. She also organised somebody for my check-in and called me a taxi to the airport. Also extending my stay once more was totally uncomplicated. I also had a very nice flatmate and got some useful information about Catania.
The flat is wonderful and maybe the most stylish place I've ever been to :) Everything is lovely furnished and you feel like at home. It's a little bit noisy at night since the flat is located at a busy street but in return you are in the middle of the sicilian life of Catania. Grazie mille!
