Marco is an incredible host. He met us at the apartment and he even tried to meet us midway as we were coming from the station. He was gracious and told us all about Testaccio and all there is to do in Rome. Marco even had pamphlets and local information all printed out for his guests. The apartment was exactly as described and Testaccio is a great place to stay as its away from the crowd/tourist area and you get a sense of what it's like to live in Rome. Testaccio has nice markets and restaurants within a 5-10 min walk. With the bus line and train being close, its easy to get around. We even took a 50 minute train ride to the beach (Santa Marinella) If we return, we will definitely stay here again!!
