We got really good instructions how to get home from the airport and also a list of suggestions where to go and where to eat in the city. The apartment is about 30 minutes to the center. The neighbourhood isn't very romantic, but there are also some places where you can eat and a supermaket. We really enjoyed our stay!
P.S: We recommend to make a resevation for some attractions (villa borghese, the tour inside the colloseum, etc.)
