We had a real pleasant stay for three nights! Hans is a great host and the Nautilus a real lovely boat! Once you come to Rotterdam you should try a stay on this boat! It is full of lovely little details and romantic lights. It's a great experience to live on a houseboad with all the bigger houses of a town around you. Also it lies in walking distance to the city center. We had a wonderulf sleep with the swaying of the waves and we loved to take our breakfast on deck while observing the seagulls around us. It's highly recommended by us.
