What a unique experience! The hosts were very hospitable with their good suggestions of things to do and also with helping open a sticky entry lock.
My description of the houseboat is a sensory one: the sounds of gentle rain on the roof of the houseboat, streaming jazz while watching the comings and goings on the canal, the ringing of the Westerkerk bells every quarter hour, hot shower in a tall bath tub, local brown cafes such as Cafe Chris close by, cool winter night snuggled under the bed covers-all in all a very special experience with a great location.
As mentioned in other reviews, if one has mobility concerns the bath tub might be hard to access.
