We were greeted by Sergio's sister-in-law Luciana and she was very kind. Margherita showed us to our room and gave us a map of the city. Everything is very new and trendy. There is a kitchen for everyone to use and we had a private bathroom which was a separate door in the hallway. The apartment was a 10 minute walk to the nearest subway station, a 10 minute walk to the tram, and a 30 minute walk from the colosseum. We took the Pigneto line which connects to Lido and you walk about 1,000 meters to either Re di Rome or San Giovanni on the main metro line, red. Overall a very nice stay and I would highly recommend staying here.
