We had a wonderful time in the Palazzo Cattolica Apartment. The location of this apartment in the old and majestic Palazzo right in the middle of the Kalsa quarters is probably one of the best in Palermo. The apartment itself has everything you need. Beds are hard but ok. The terrace in the picture is not a part of the apartment itself, but can partly be used and is a pleasant place to relax. The owner Antonio can and will give you all the information you need including a guide of restaurants and others places of interest that was really useful.
I would certainly recommend this apartment to others.
