About the best way to arrive at home: from Fiumicino the taxi cost 48 euros or you can take a trein to Ternini station and take a taxi from here to home cost only 10 euros and you arrive in 5 minutes, but if you want a cheaper solution you can take a lot of bus to corso Vittorio Emanuele and stop to piazza della Chiesa Nuova, from here you walk 3 minutes and arrive to my home, so you spend 15-20 minutes.

From Ciampino the taxi cost 38 euros and from here you can take a bus to Termini station.
