Claudio's apartment is in the centre of Palermo just a couple of minutes walk away from Teatro Massimo so it is very easy to get around Palermo from here.
It's in a lovely recently converted building and even has a lift, the road is very quiet and the flat looks on to the gardens so there is no noise at night. The flat is nicely decorated with modern furniture, a lovely little terrace with table and chairs, fast wifi, kitchenette with all the essentials. My parents slept in the double room and said it was very comfortable, I slept on the sofabed in the lounge which was also very comfortable.
Claudio replied to my emails very quickly and came to meet us at the flat (with a bottle of wine in hand, grazie Claudio :-)) and he called to make sure everything was OK with the flat, very attentive.
I would recommend staying here to anyone who wants to be in the centre of Palermo and knowing it is somewhere quiet and safe.
