We stayed in the house attached to the garden so were able to wander round at any time of day or night. Visitors enter the garden through the house although there are only a couple of rooms open to the public so the house itself is only 5 or 10 mins at most. The main point of this place is the garden which although it is only a couple of acres is worth an hour or so for a good look round or longer if you wish to sit on one of the numerous seats and relax. There is so much to see in such a small space, the garden being planted in a series of rooms. Most of the garden is formal planting but there is a large vegetable plot and a wild part with a great tree swing for young and old kids.
This is a great place to come for a look around and maybe a coffee before going to one of the other nearby NT places such as Montacute (10 mins drive).
The cafe looks basic compared to other NT properties although we did not try it but would say it is ok for coffee and cake but not a main meal.
