I had a lovely stay on Sander's houseboat. We were proactively contacted the day we landed ,and were welcomed warmly when he arrived to the boat. The room was stocked with coffee, some drinks, and even a snack. We were shown how to use everything and Sander even brought us an extra heater suspecting we may get cold having flown in from a more tropical climate. It rained a lot during our stay but you wouldn't have been able to tell from inside the suite. There was no rocking or noise from the wind, everything stayed quite cozy. It was very easy to get anywhere from this location as there were several metro and bus lines a few minutes walk away.
Overall we had a wonderful trip made even better by the thoughtful and proactive actions of our host :)
