Once we got there, Marco's brother: Daniele was already waiting for us there. After we got inside the apartment, Daniele gave us a complete introduction on Rome, which made us feel really nice. We followed Marco's recommended-place-to-eat, and all of them are great!
A coin laundry was next door, two supermarkets were nearby, bus and metro stations are in wallking-distance, a very convenient place to enjoy Rome. I will definitely choose to stay there again!
