Reinhart was a fantastic host. He was pleasant, welcoming and informative but not in an intrusive way. We loved the large bar of chocolate which Reinhart left for us on arrival. The house boat is very stable considering it was quite windy while we were there (early February). Inside it is light and airy and has a funky feel to it. You have to get a ferry from Centraal Station but they are free and leave every 5 minutes so getting there is absolutely fine.
