The houseboat is awesome.
Me and my friend had a very good time.
For starter, it added so much to the Amsterdam experience. You live on a boat on the inside of the canal - this means you get to see all the tours and tourists that are going through when chilling at top of the boat.
Aside for that, the place was very clean and comfortable, and the location is great.
Daan is very responsive via WhatsApp/messaging.
We had an issue with our flight that got postponed. Daan helped us and found a different boat to stay in for an extra night (it was relatively small, but it served out needs for the extra day).
I would recommend to anyone to have an Amsterdam experience in a boat, and this boat was really a treat.
