I stayed for a month in Mattia's place in Catania and I felt so much at home there. It has everything you need for a long stay. Well equipped kitchen with all the cooking utensils as well as some cooking basics (oil, sugar, salt, vinegar, coffee) The home is comfortable and clean and feels secure with the entrance in a little shared courtyard with friendly neighbours.
The location is great because it's a 10-15 minute walk to the main street where all of the things you would want to visit as a tourist, but it is also in a very local neighbourhood where you can find local (and less expensive) bakeries, pizzerias and restaurants for a more authentic Catania experience.
Mattia and his aunt Germana went entirely out of their way to ensure I was comfortable and had everything for my stay. They answered everything very quickly and were kind and funny and very welcoming. I would 100% recommend this place.
