Bart was extremely accommodating with schedule changes. He met us in Antwerp and drove back to holland to see the outskirts of amsterdam. He took us to the lovely town of delft, saw windmills and even visited a family owned cheese farm. Bart was knowledgeable and was very informative about the surrounding areas. He even made sure that we made the train back to Antwerp. I would highly recommend Bart if you are visiting amsterdam.
