Merlijn's boat was a unique experience to stay in Amsterdam. The boat is very confortable and we enjoyed the terrasse. The view is perfect, and the neighbourhood very quiet. Tram, metro and train station are within walking distance and take you directly in the center. You can park your car easily in the street. The parking is quite expensive though (like everywhere in Amsterdam I think), 32€/day but it's free on sundays and holidays. I would definitly recommand Merlijn's boat if you are planning a weekend in Amsterdam!
