Staff is unprofessional and rude.
When I parked a car, I signed a form which did not show any additional charges. However, when I returned, the staff demanded an additional charge and only in cash. I was lucky I had enough, otherwise they told me I would need to go back to the airport to get cash from an ATM.
You have to leave a key in the car unless you make a deal $$$ with a guard.
Cars are parked very close to each other. My car was scratched on one side. So, do not be surprised if you get a dent or scratch upon return.
The only good thing was a transfer. We wait about 10-15min when we departed and about 10min when we arrived.
