(+) The location of this appartment is really stunning: via Crociferi is a beautiful and quiet street, and you will be very close to Catania's hot spots: a short walk will bring you to the shopping street via Etnea, the vibrant fish market, the sunny Bellini park, the authentic Catello Ursino square, and more!
When you wake up in the morning, you'll have a view on the sun raising on the sea and the roofs of Catania. The place is suitable for remote workers, the internet connection is decent, and the living room is large enough to invite people for aperitivo. The kitchen has most facilities you need to cook (after travelling in AirBnbs for a while, I was very happy to find stuff like a real cooking knife and a kettle!)
The place is really quiet, you won't hear noise from the streets or from the rest of the building, only the sweet bells of the churches around, and a few pigeons on the roof.
(-) As I visited in winter, the place didn't cope well with cold and humidity, but that seems to be pretty common in Sicily.
If you're coming for a long stay, be aware that you will get only one item of each disposable equipment (1 toilet paper roll, 1 detergent bag, etc.), for more you'll need to buy them yourself.
Overall it was a good experience.
