The pickup location was very far from the actual spot, and they didn't have a counter inside the airport. My SIM card only had data but couldn't make calls, so I couldn't find anyone and had to buy another SIM card to contact them. They initially said Entrance 10 in the Arrival Hall, but after several phone calls and moving around, we finally met at Entrance 8 in the Departure Hall, wasting an hour. If you don't speak good English, it might be really difficult to communicate. To avoid uncertainty in your travel, I strongly advise against renting a car from KPN.
