It is advisable to look up the rental car company before picking up the car.

This company does not have a counter at the airport. Because we arrived earlier at the airport it was very difficult to find out where to pick up the car, after making several inquiries from other at other counters we were told that a bus would should up in the parking lot at some point. by going on line we were able to find a main number in Lisbon and called it, after a 15 minute wait the agent told us that the bus would be arriving in 10 minutes. Half an hour went buy and still no bus, finally we were able to locate a local number and managed to arrange for a pick up to their location a few minutes outside the airport. When we got to the rental location, we were told that our car was not available because we were an hour early and the only choice was to take an upgrade for an extra 60.00 Euros or wait an hour, we agreed to pay the extra since we had to be somewhere quickly.

The booking platform is great. The only comment would be to clarify where the car rental company is. Also if you could specify costs for an additional driver.
