Andrea's place is very comfortable to be in.
There is a wonderful fish cafe near the local fish market, check it out. Grilled tiger shrimps there are amazing.
If you want to swim in the sea, check for swimming bans for beaches you are interested in. The beach near the Norman Castle (Aci Castello) is closed since 2019 because of a rockfall.
The beach nearby from Jun 2020 - likely because of the COVID-19 thing going on.
