I highly recommend Valeria's apartment. After a different host canceled unexpectedly, I needed some extra help. She was flexible with check in, gave restaurant advice, and was easy to contact when I needed to. The apartment feels spacious, the air conditioning works great, and it had what I needed for a few days stay. From the apartment it is about 5 minutes walk to the water or to the main part of town (where I can recommend you visit Viscuso for some delicious treats). The bus stop to Catania is just a couple of minutes away.
