We stayed two nights at Antonio's place in Palermo and it was an absolute blast.
The apartment is pretty big, with large living room, bedroom, two balconies and one big terrace on the roof. There is also small, but well equipped kitchen and washing machine. Location is amazing - right on the main touristic street with anything in center in the walking distance. Antonio is wonderful host helping us with the place to store luggage early in the morning, and was pretty flexible with check-in/check-out time as well. He also provided us with some pretty good local tips about the city.
The only thing to note about this place, is that you would have to climb to the 4th floor with no elevator, but it's totally worth it :)
