What is the best and cheapest way to get from Rome CIA airport to the hotel ?
If CIA means the Leonardo di Vinci, take the train to Termini and then a short cab ride.
Taxi transfer through the hotel 60€ straight to the door. We traveled as a family of 4 and lots of suitcases so it was easy and painless.
I would suggest a taxi as the Hotel is tucked away from the main road and can be a bit of a trek with your luggage. A taxi can get to the main square directly outside the Pantheon less than 100 yards away
Taxi or transportation organised by the hotel. Trying to save money by going by train and buses will take forever and you have to drag your suitcase quite a bit as there is no bus stop near the hotel.
