We used Rome in Limo in Rose a couple of years ago and loved them. We did Rome in two days, and we got into places most people don't get to go. We had personal service in the Vatican, and were picked up 20 ft outside after the papal blessing when most people had to walk blocks and blocks. We had a personal guide arranged by them through the Vatican Museum.
I would recommend Rome in Limo to anyone visitng Italy in any of the cities where they are.
