Really a 5-stars stay.
The place is well located, easy to access (just one floor of wide stairs), fully equipped, warmed, very spacious, and well decorated. Internet connection (for remote working purposes) was great too.
Communication with Francesco was very good too, he answers quick within minutes, and he's polite and helpful.
I have been stayed in almost 30 airbnbs in the past, and this is apartment is located in top 3 for sure. Really recommended to visit Palermo.
