We had a great stay in Walter's apartment. Walter is a friendly and helpful host. The apartment is clean and has all the basics. It is in a great location, right next to the metro (Piramide station) and train (Ostiense). It was an easy train ride (8 euro) from Fiumicino then only a two minute walk to the apartment. It's about 10 minutes walk into the heart of Testaccio which has incredible food.
