The Apartment is clean and had all the necessities we were looking for, including an AC (actually there are two, one in the sleeping room and one in the kitchen/dining room) and small but well equipped kitchen. Also you'll find a small balcony on the inner side of the building - we used it for hanging our laundry out to dry. If you have neighbors (on the other side of the balcony is a another apartment about 2m away) you might need to keep the shades of the balcony doors shut to get more privacy.
The best part of the apartment is the location since it's right in the beautiful old town of Palermo where you can reach all the nice bars and restaurants easily be feet.
The communication with our host was also just perfect.
