If you've always wanted to spend a day or two on a house boat, and whilst you are in the Rotterdam area, get in touch with Hans and book his place! Hans is a great host, he will welcome you on board the 'Nautilus' with a cold drink, before showing you around. Once you have visited the boat and unpacked your stuff, Hans will give you a short but accurate briefing what to do in the city, and where to find nice beaches not too far away. Rotterdam is definately a very interesting city to discover, and in the evening, after a busy day and a nice lunch in one of the restaurants in the vicinity, you will appreciate the intimacy of your (momentary) home, that offers just everything you might expect, at a very competitive rate.
