I don't recommend this service. Our driver was constantly texting and IM on Facebook while driving us on the highway and winding roads of Malta. When we kindly asked her to not to text and drive this clearly pissed her off.
Safety is not their priority.
We struggled to identify the driver at the airport and walked to the welcome booth where the man told us the driver had been waiting for us and directed us back to the line. We had assumed the driver would have been displaying our names. We were mistaken. The man in the welcome booth was angered by this and began yelling and exited his booth to show us where the man was standing. The driver then had to ask people In the car park about the location. He then found the street but not a pleasant experience.
