It’s great.
The architecture is great.
The history is great.
The food is great.
The weather is great.
We had a few days there a couple of years ago, and stayed in Syracuse/Ortigia - which is just stunning. From there we also had a day trip to Noto (absolutely beautiful - highly recommended), and Etna (it’s a great big volcano, brilliant).
We never made it to Palermo.
