Stijn has an amazing place, I would definitely recommend taking the opportunity to stay there. The houseboat is beautiful, with an awesome outside seating area (equipped with heaters for the winter) that looks out onto a lovely view. The location is perfect, quiet enough that you are able to get rest whenever needed, but only a 10 minute walk from the fun of the city centre.
Stijn is also a great host, happy to help you out with anything you need.
