Great spot right near the center of Haarlem. Toilets and sinks are available. It was clean and in good order. Entering and exiting the grounds with the camper works fine with the code. Nothing wrong with this place. And yes, you can hear the traffic, but that is logical given the location. There are trees at the edge. If you place a lot of value on a cozy atmosphere, then this might not be the right place for you.
