From Termini: Upon entering the main hallway, turn left, towards the Via Giolitti-exit. Outside, turn left again and then right (Via Gioberti). Walk on till you come to Santa Maria Maggiore (a huge basilica) and turn left onto the Via Carlo Alberto. At the end of the street turn right and then take the second street on your left. This is the Via Ferruccio. Look for number 30 (just past the SPORT store) and buzz apartment 27 (the Little Italy).
From Ciampino Airport: Take the bus to Anagnina and from there the metro line A to Vittorio Emanuele. Follow the signs for the Via Buonarotti-exit. Turn right and then immediately left when you come up (Via Buonarotti). The first street on your left is the Via Ferruccio.
You can also take a (more expensive) bus directly to Termini. In that case, follow the previous directions.
From Fiumicino (Leonardo da Vinci) airport. Follow the signs for the first Via Giolitti-exit and, after brushing off the taxi-drivers (it is really only a 5 minute walk), cross the road a bit to the left and walk straight ahead till you come to a park. Turn right and then left. The second side street on your left is the Via Ferruccio.
A taxi from either airport should cost you no more than 50 Euros. Ask the price first and if you are charged more than that, just wait for the next one in line.
