Jaap was a very helpful host. He gave us an extensive introduction to the apartment. Everything was very clean and well equipped. There is a lot of information material about restaurants and sights. Jaap has a page where current events and information about Amsterdam can be found. All this helped us a lot to make our stay nice. Also, Jaap helped us when we had difficulties with the return journey because of a train strike. Nice accommodation and a nice host. 5 Stars
