The museum consists of ~20 rooms, each with a small number of high quality paintings. There is also a lovely knot garden in the centre of the buildings, and a lovely grand dining hall, with furniture contemporaneous to the Golden Age. There is also a fabulous dolls house and bed hangings in a separate room (no disabled access for this).
Main problem is lack of parking. I dropped off my wheelchair user, and left her alone whilst I parked the car 500m away and walked back. Then repeated the exercise at the end.
