The Wikkelboat is a great idea to experience another way of living. We were surprised how much fun we had in those two days, especially with the hot tub (I wouldn't pass this offer in my eyes). We had everything we wished for on the boat - a coffee machine, a grill, a dishwasher, ....
Since it was our first time in Rotterdam, we were very gladful about our location. We literally walked 5 minutes to the markthal and maybe 5 more to the centrum.
Even though it was a bit pricey, I 100% can recommend the Wikkelboat!
