You will land at the airport of Palermo - Falcone Borsellino
You have to take the bus, there’s one every 30 min. You can get off at the stop via Roma 256 (45 min). Afterward there is about 4 min. by walk from there. The ticket costs around 6 €. More information here. A cab costs 45/50 €. We can also provide you a personal driver. It will cost 30 €, to pay directly to the driver.
With the car, remember that the street is pedestrian from 10 a.m. till 7 a.m., so it's easier to write on your gps "via Napoli" that is in front of our door.
We don’t have a private parking but there are plenty of streets with parking space around. During the week, from 8 a.m. to 8 p.m. it is a paying area more info here.
