I like Giorgio's apartments: few steps to everything, very very clean and big. Kitchen is full of everything you need to cook your perfect Sicilian dinner :) aparts are big, two airconditions (in main room and in bedroom), comfortable bathroom with shower. We liked table and lamp over it.
And few words about Giorgio as owner - he is the BEST! Knows everything, gives all information you need, and even has small library in his aparts. Was nice to find bowl of local peaches and beer in fridge. So, yes: I recommend him and his apartments in the center of Palermo.
