Great little apartment with a great location. Local restaurants and bars are all within walking distance. A few bars directly downstairs offer cocktails at 3 Euros per glass. The apartment is private and quiet, you won't hear anything from the bars downstairs.
The apartment itself has a very chic design and it contains everything you need with good air cons (2 air cons, in fact) and a decent shower.
Giuseppina and Sandro are great hosts. They were helpful and accommodating to our requests. I definitely recommend her place if you are visiting Catania!
