From the airport, take the public bus (approx. 6-7€) and drop of at Piazza Politeama (ask driver).
From here it's best to walk - approx 1.5 km - see map(s). You may want to print this out. (Felix and myself are on the easyjet flight).please ignore earlier post which porposed route via central station - not good as full of thieves.
