We had a great stay and I would recommend this to anyone. The room on the boat is lovely, clean and warm with a private bathroom and shower. We were warmly greeted but didn't see anyone until we left. This was down to our hours and not meant as any criticism. It was made clear that if we needed any help all we had to do was ask.
The houseboat is at the end of a quiet canal and you could really enjoy this in the summer, our trip was mid winter so we didn't spend time "on-deck". The location is great for getting into central Amsterdam with short walks to the tram. We also found some nice cafes and restaurants near by. In summary, a lovely place to stay and ideally situated for the city.
