Probably one of the best hosts I've ever met in my travelling life. He didn't charge me for my very late check-in (after midnight) and he offered to share with me a bit of the Palermo nightlife, which spreads throughtout the magical districts of la Kalsa and la Vucciria. He's very helpful and he will give you lots of advices on the places you've to visit and the restaurants you've to eat in (very cheap but good trattorias and osterias). Highly recommended.
