Daan (pronounced "Don," not "Dan") was very helpful when we didn't understand how to turn on the hot water in the shower and when the wifi went out briefly. We had plenty of everything we needed -- lots of bedding, plenty of towels and toilet paper, and a lovely kitchen and a bathroom which was tiled from floor to ceiling -- amazing on a boat!
We loved, loved, loved the location. What a treat it was to stay on a houseboat right on a canal in the middle of town. Daan's houseboat is highly recommended!
