We had a family Sunday lunch here and then stayed overnight. The lunch was lovely, in a grand setting and with excellent service.
We had a small room on the mezzanine floor, but it had a separate living room with a TV and was very pleasant. Our only criticism would be that the bath had only a hand shower and no curtain or screen, so if you just wanted a shower you couldn't avoid getting the floor wet. This may not be true of other rooms.
The breakfast was good, except for the avocado on toast, which was mushy and unappetising.
The house is impressive and has a fascinating history, and the surrounding parkland is lovely, and well worth walking around.
