I really enjoyed staying on Stijn's house boat, the unit for guests is really nice, clean and spacious (only me). The location is really convenient to the main train station, about a 10 minute walk. I was able to walk to all the areas of Amsterdam I wanted to reach. The only thing, kinda minor, is that you need to cross 4 house boats to get to your section of the houseboat. The route was a little confusing the first few times I returned to the house boat from the city, especially after a visit to a coffee shop. Stijn gave me a few food recommendations during my stay that were great.
