We have stayed at the San Luca Palace Hotel (yes, only one "c"). It's a very nice hotel and the staff is exceptional. It is located about 150 meters inside the city walls. Even if you don't stay there, go there for an aperitivo. They serve actual hors d'oeuvres, the best!
We had a car there and you can get to their parking lot without entering the ZTL. And it is very safe, they share the lot with the Polizia!
