We visited Jans houseboat in the middle of May and where charmed by their lovely home. The boat comfortably slept the three of us and the surroundings are very peaceful. Jan met us at the boat early and showed is everything we needed to know. The boat is a little distance from the center and Jan offered us the use of 5 bikes ( we weren't brave enough). You can walk into the center but it takes about an hour but the walk takes you through a beautiful park. We got a taxi back on the first night and this cost us almost €30. The best mode of transport is the tram (16 or 24) which drop you off a few minutes walk from the houseboat. I would highly recommend Jans houseboat and will be sure to use it again if I am in Amsterdam.
