I stayed 3 nights on Daan's houseboat together with my wife and two friends of us. Daan is a very friendly and likeable person and gave us useful hints for our stay. Contact to him was very easy as he responded always promptly. The boat was clean and warm, even with night temperatures around zero degree. However, the boat was somewhat older than we expected. Not perfect was from our point of view, that the door to one of the bed rooms did not close, the other bed room was relatively small for two people and also noisy because of the sewage pump underneath. Nevertheless, Daan's accomodation has this special houseboat 'flair' and the advantage of being located almost in the center of beautiful Amsterdam.
