Viviana's appartment is located nearby Rome train station which offers trips from and to Fiumicino airport. It is thus very convenient to travel quickly and at low cost from Rome to Fiumicino airport and vice versa.
Beside next to this train station there is a subway station. This allows you to join touristic places very quickly.
Last but not least, Viviana place is very clean and confortable and the welcoming by her mother is great!
Enjoy the stay and have fun.
