The apartment and the location were perfect. A few minutes walk to the main Old Town area, with plenty of bars and restaurants nearby and the main street only 5-10 minutes away.
The main station is nearby too for trains and busses to nearby cities for daytrips, which was very handy.
Then apartment was very clean and comfortable. Our flight in to Palermo was delayed and the host was still able to meet us, even though we didn't get in to town until after midnight, which was very nice of them.
I'd definitely recommend staying here if you are visiting Palermo.
