For us the romantic aspect of a houseboat disappeared immediately by the overall looks of the boat.
Nice was that we could use two bicycles in fair condition and that Edith offered for us to leave as late as we wanted.
The turnoff factor for us was the bathroom and specially the toilet which was difficult to flush....and to use the sink in the kitchen to wash your face, brush your teeth and shave without a mirror. For this camping style accommodation the price is simply too high.
