Grietje and her husband are welcoming, nice and helpful. We had a very great time on this beautiful boat with all our family. It's 15 minutes from the central station with the ferry (free and numerous during all day until late) so that's very easy to live in the boat, and visit the city. They even booked the taxi for us the last day and got up at five in the morning to be sure the taxi's coming. Thanks a lot for everything, that was great !
