I'd give two stars because the drivers were pleasant and on time but they lose three stars because I was quoted one price and then advised near departure time that there would be additional charges for the Mont Blanc tunnel (more than 100 Euro additional) on top of the agreed amount. I complained but the company could not clarify due to the limited English of the company's representatives. They also lose a star because I was asked to pay the full transfer fee at the end of the first leg. I paid half the amount at that stage, in cash because they have no credit card facility, but that could not provide a receipt. They also a star because we drove for a long distance through local congested roads in Italy when we could have been driving on a fast motorway that ran immediately alongside, presumably to avoid tolls. Would I use them again? Definitely not!
