I believe that taxi's are regulated in Rome. From the airport (Leonardo da Vinci) to any point in the city is no more than 50 euros.
There are options and websites I find helpful is To and From the Airport.com and

and then there are the limo services such as Rome Limousine Tours from Rome Limousine Service, Inc. |
