Me and my boyfriend stayed 3 days in Palermo at Alessandro's place. The apartment is in a very good location, near to the center, easy to reach every tourist attraction by walk. It was also easy to go there in the evening. Alessandro was very helpful, he showed us how the key works and there was an itinerary with the best tips on restaurants, what to see inside and outside of the city, where to shop things, etc.
We had a real italian family in the neighbourhood, I loved listen to them in the evenings as they were talking to each other, which seemed that they argueing :-)
My only problem was that it was very cold in the night, there were no heating and we couldn't found blankets, only bedspread.
