To stay at the Waterwolf was a very nice experience. The ship was nice and tidy and clean and big enough for a group of 17 as we where. It was easy to get in contact with the host, and we got all the information needed for the stay. The ship lays a bit away from the centre of Amsterdam, but there is a free ferry that takes you to the centre in 15min. Everything worked out perfectly for us at the Waterwolf. I will certainly book this ship another time!
