Really loved Alessandro's apartment, very comfortable beginning and end to the day in Rome. Clean, homely, and amazing air conditioning. Alessandro's wife greeted us, and assured us if wr needed anything we could ring their apartment or message Alessandro. This made us feel very secure.
It's only a 15 minute walk, and a 5 minute bus to Ostiense station - just make sure to buy the a 1.50 euro Metro pass from a Tabacchi before boarding, it gives you a 100 minutes of travel on the metro. So cheap! Had a great time once we got a handle on the metro, google maps helped us a lot :)
