Very original and cozy experience sleeping at the Avontuur in the middle of central Rotterdam, but still in a quiet location. Easy to walk to most of the main attractions in the central city.
Both Premala and Wendy was nice hosts and even though you share the boat with them and other guests it doesn't feel crowded at all. The cozy room it bigger than the picture says :-)
The reason only 4* and not 5 was due to the extreme summer weather and the very little window making the room very hot. We had a fan, but still... In a normal summer it would be a 5*
