Working at the KLM Open golf, I wanted to stay somewhere convenient to the course and the centre of Zandvoort, and this fitted the bill.
The owner, Carla, is very accommodating, and takes good care of the guest house.
Rooms are themed. I stayed in the Black and White room which, while small, was well decorated and had everything needed for a working week.
If there's more than just one of you then go for a bigger room. You effectively have to walk sideways into the toilet/shower room.
Parking's an issue nearby, but Carla has a permit which she'll hand over. Bicycles are also available. The town centre is a mere three minutes walk away.
The price is a little steep for what you get, but was fine for the week I was there when so many rooms are booked up more
