The houseboat is a nice place (everything was very clean and new - and even has an outdoor area to relax) in a great location (It was easy to go for anywhere in Amsterdam from there, besides that, very safe and calm). We didn't meet Diewert when we arrived, but his wife, Wieke, was very friendly with us and helped us with tips and explanations about the place and the neighborhood. And when needed (before, during and after), the communication was very fast.

We enjoyed our stay.
