The location is great, in the middle of city center and the apartment is just perfect. we even had some breakfast stuff for us in the morning. Ezio was very nice and waited for us (we arived later than expected) and there is a big parking nearby that sometimes is free.
Overall palermo is famous for nightlife so if that's what you're looking for, this apartment is close to everything.
we went at the end of march for a city break, and it was pretty crowded, the water was still too cold for swiming but we had a lot of fun.
