Everything went fine. Michele is very helpful and responsive to text messages. The apartment is good and comfy, though the room upstairs is extremely hot (we stayed there in the last week of July), so we took the mattress downstairs. The AC and fans were great. The building itself is literally in the middle of the historic part of Palermo, 3 minutes walk away from a nice street with restaurants and shops, which was great for our evening strolls.
The apt is well equipped for a shorter stay even to wash some clothes and iron shirts, etc...
