Zwijndrecht is just across the river from the oldest city of Holland: Dordrecht, with many monuments, small harbours. Owner guides people there. Rotterdam, in the Lonely Planet top ten list of vcities to visit, takes only fifteen minutes by train. Keukenhof by train and bus circa one hour. Amsterdam one hour. Kinderdijk (windmills) at close distance, half hour by car or from Zwijndrecht by ferry!
Make yourself at home! Just a few rules: no smoking inside the house, no drugs. Behave in a normal way, as you would expect yourself.
