Anna communicated clearly to answer my questions beforehand, the staff were very kind, everything was very clean and well attended to, and it was easy to reach the Colosseum and the fun little street by it with a bar, restaurant, gelateria etc.., and not too far to the downtown area (10-15 minute walk to nicer restaurants and live music Sunday night etc). Trevi Fountain is a 20-30 minute walk, Vatican maybe 45 and the Porta Portese market about an hour. Would definitely recommend :) Just keep in mind that taxis charge 48 Euros from the airport, there are 2.5 flights of stairs to climb if you don’t want to smush into the small lift, and there is a fair hill to climb in the park when coming back from Colosseum so bring good walking shoes! :)
