Beautiful, modern apartment in a great central location. Lots of restaurants right outside the apartment. Having a parking spot in the same building was great, though do be aware that driving in Palermo is quite challenging, with hectic and narrow streets. We managed with one person driving and the other navigating (though at one point the navigator had to jump out to make sure the car would fit through a narrow alley).
Aldo was super friendly and helpful throughout the whole process. He gave clear driving directions, met us as we arrived, showed us the apartment, and then explained how to register our car for the ZTL (restricted traffic area). As another example of the host's thoughtfulness: we were traveling with an infant, and we arrived to find a baby cot had already been set up, even without us having asked for one!
