Francesco is great host who gave us some definite added value by picking us up at the airport and bringing us back there (20€ for two people each way) - that was super nice of him and allowed us to save some money and time. He gave us lots of local suggestions that helped us maximising our stay.
Re the apartment: if you are spending just one night in Palermo it's ideal. You get what you pay for. It's very cheap and centrally located. That is great. The bathroom could definitely use a refurbishment and a deeper clean. Towels and sheets didn't smell clean; I suggest you bring your own. All in all great location and great host!
