The houseboat is AMAZING.
It is much more spacious than I had imagined, and it was very well equipped. The Murphy beds were very comfortable and easy to use.
The location is VERY central to many fun and interesting things to do in Rotterdam. It was very easy to access from the Blaak station (one stop away from central station.
The hot tub was super fun and relaxing - a great way to end a day of biking and exploring around the city.
I highly recommend!
