Lovely Apartment in the old city. You are literally right next to the Palazzo Reale and the Cattedrale.
Would recommend for one person, two persons maximum (the bed is 140x200cm).
When arriving via plane at Palermo Airport (Punta Raisi), you can take the train to Palermo Centrale and get off at "Palazzo Reale", from there its just a few hundred meters to the apartment. Would NOT recommend to arrive via car. Traffic in Palermo is horrible and there are virtually no parking lots.
Fazit: Would highly recommend, if you are a single person or a couple, arriving via plane or train. Would not recommend, if you are more than two persons and/or arriving via car.
