It has been one of our greatest trips to a metropolis ever thanks to the stay with Frank and his family on their boat. To live on a boat was a great experience and all there has been perfect (the bedroom is very comfortable and clean, the bathroom too, the nespresso-machine is wonderful for a comfortable coffee to start the day, the guidebooks all around have given a lot of helpful informations, the chocolate as a guest-gift was such a nice touch and all the other lovely details...) and we are sure that we come back, if we are welcome as guests again.
