I used city-airtport-taxis to get from AMS down towards Maastricht, and it was a great experience. The initial booking was easy, and when my flight was cancelled at the very last minute, I was able to email and update my arrival (even though it was technically within the 24-hour "no amendment" time period) and adjust the time the driver would be at the airport. Upon landing, my driver got in contact with me, and I was able to message them as we got through passport control, luggage etc. They waited during this long process and then drove exceptionally well through the Netherlands. Fully recommend this service.
