Marco was a wonderful host. He met us at the bus stop when we arrived and gave us a lot of useful information about the neighborhood. He also helped us when we couldn't find a taxi on our departure, even though he was on his way to work. The Testaccio neighborhood itself has very few tourists, but is still residential. It's very close to Trastevere, and the rest of Rome is very easily accessible by bus or metro. The bedrooms are very large, and the kitchen is well equipped. The apartment felt safe. Overall I would highly recommend this property, and I would like to stay there again.
