Derk is a very nice host. Communication was very easy. We met him at the boat and he explained us everything. He even gave us some tips on the area.
Although it was not the cleanest accommodation, we had a very good time on the boat. In the evening you can sit outside on the deck and enjoy some beer. The boat has its own charm and definitely a cool alternative to a hotel.
The area is super nice and central. A lot of nice bars and restaurants are nearby, and you can nearly walk everywhere (Vondelpark, Museumsplein, Flower Market)
We definitely would come back. 
