Car park P4 is located 100 meters in front of the terminal exit and is nothing more than a portacabin and car park which has been assigned to numerous car rental companies for their operations including the eight featured on car hire Faro airport.
This may have been a temporary arrangement that has become more permanent but in peak times the facilities of the office are not good enough for the high volume of customers. To find the car park forget any car rental signs and simply follow the signs for the car park P4. Go through car park P2, carefully crossing the dividing roads, up the ramp and around to the office in P4.
With space at a premium in the office, your party members and luggage will have to remain outside and the signs for the various companies can be confusing as it seems everyone works from the same desk. The staff are friendly though and understand the limitations of the facilities so do feel free to ask. Bring water for any wait in the sun and some shade if you have it with you. You can always allow your party to wait at the cafe in the terminal while you pick up the car and then come back for them, there is no rush to leave the car park after check out. The cars are all on site and the exit is very easy and takes you around onto the main exit roundabout. When returning the car enter at the main entrance and look for signs for P4.
