I was travelling to Palermo for a couple of days with my Partner and a friend. We really enjoyed our stay in the Apartment. It is located within or at the border to the old town. It is very spacious,and an absolute plus are the two bathrooms. Some people were commenting that it is loud. For me, living at a busy street anyway, it was ok. If you are sensitive to traffic and ambulance noise, you should sleep upstairs with no window facing the road. The beds were super comfortable and the kitchen well-equipped, there was a Bialetti for preparing coffee but a water kettle for preparing hot water for tea would be nice as well (boiling it in a pot worked as well though :) ) the only thing that bothered us was the smell in the hall when entering (after turnig on the heating ) We couldn't figure out if it was the drains or something else. In the living room and in the bedroom it was ok after closing the doors and opening the windows for a while.
Anyhow I can totally recommend a stay.
