We stayed in Arnout and Brenda's place while visiting Rotterdam for a Triathlon. They were very friendly and helpful, Brenda greeted us with a pot of tea ready on arrival. The place is homely with a great kitchen and living area space, perfect for us to prepare and relax. It is in a nice location, quite but only 20mins by tram to the centre of the town. There are also supermarkets, shops and nice places to get coffee within a short walk. We had a great stay and would recommend their place, there are some steep staircases to keep in mind if you have access requirements.
