Great service at the Amsterdam Central Station branch.
There is a 10 mins walk from the branch to the car collection location. It was a very good weather today, but when it’s not, it must be a hastle.
Now if you are trying to use Sixt sharing service download the application wayyyy before you come as there is a lengthy online process to upload documents, ID’s, passport and take some selfies with no possibility to upload documents, they must all be physically available and handy.
