Lovely home; peaceful, comfortable and well appointed - had everything I needed. I wanted somewhere outside of the city where I could travel to other places from so this was good for me. It was a short drive from Ciampino airport. Alessandro was extremely helpful and accomodating when I needed to check in late. He's a good host!
Regarding transport, I had a hire car and I didn't use public transport but I got an Uber to the Colloseum one day which cost 30 euros. A taxi home from the north west of the city was 45 euros.
