To stay on board of a pirate ship in the middle of Amsterdam was an experience for our nine year old daughter. Ducks became close friends and to watch the boattraffic on the Amstel river is wonderful. The boat is cosy and functional and we absolutely loved the decoration as well. You can easily walk downtown or, even better, do what the Dutch do and hire a bike.
The reception was punctional and host responded friendly and fast to sms, even during a wordlcup game.
Very recommended for couple or couple with kids, or writer of historical novels.
