The apartment is right down in the middle of the market area, so it's fairly loud and chaotic. Lots to take in there, so make sure you have the right energy to dive in. Alessio is the coordinator for the apartment - while we didn't meet, he was always friendly, prompt and informative.
Very easy walks all over the Quattro Canti area and historic Palermo. Lots to see, lots to eat...a fulfilling place to wander. The apartment is very user-friendly, just don't forget to switch on the water heater 15 min before a shower (and off again when you're done). Parking is an adventure sport in that part of town, but we always made it work.
