The communication with Hans (and his son, when he was away) was terrific, clear, enthusiastic and fast. We loved the houseboat so much — romantic, fun, exciting! Place was just as described and photographed, very welcoming and comfortable. We had a question about where to turn on the heat and Hans's son responded with the answer in under 5 minutes, even after 11pm! Coffee on the deck of this houseboat across from the market—? Heaven.
