We didn't get to see the servants quarters, just the upstairs glamourous part. We were told the kitchen has been modernised as the owners live here and all the kitchen scenes are filmed in a studio.
The tickets cost £20, a little expensive but is about average for these types of large houses as the maintenance cost is very high. Overall still worth going, at least once!
