Me and my wife did a tour with Dee (Douwe). We only booked a night before, however he was more than willing to show us around. We went on the tour being very excited. First he showed us Volendam (the fishing village). There we walked around and had some amazing fried cod. After that we drove through the countryside which was extremely beautiful and very serene. We finished the tour in the center Amsterdam where we drove around for about an hour. We were the first tourists to go on Douwes tour (through Vayable) and we were a bit cautious. Luckily it turned out Douwe is a great guide and he could answer every singe question we had. We definitely recommend Douwe!
