Henk's houseboat is pure magic, and he's a great host. You can stay in the intense madness that Amsterdam city is, or take a 10 minute bus ride and 5 minute walk to a place where you could well be greeted by Harry the Heron on your doorstep. Everything was great (though washing machine wasn't available, so if you're staying for awhile, prepare ahead) and we'd love to come back.
