Paola's place was perfect. I stayed there after I came into the airport late in the evening. I left in the morning for Rome, the train station was a quick 10min walk from her place, which was easy. I have a few cheaper AirBnBs by the airport that I stay at in a pinch if I fly in late or have an early flight (I come to Rome regularly for work), this is definitely being added to the list of those places.
