Had a great time staying in the Giovanni's place and exploring Palermo. Giovanni is a great host, very communicative, giving tips where to go and what to do. Literally he is your "virtual" tourist guide for Palermo ;o)
At check in he welcomed us with his hospitality and provided us with all the necessary information for our stay.
I definitely recommend Giovanni's apartment for stay in Palermo as it was clean, close to city center and with all the amenities we needed for our stay.
