We really enjoyed our visit. Jim, the attendant, was very nice and knowledgeable. It was a hot day and the upstairs was fairly warm. Also, if you can't do stairs you will only get to see part of it but the best part is downstairs so I would still recommend it.
The interior has the feeling of an underfunded museum ..not a historic home. Walls have been taken out making destroying the original proportions. The renovations and furnishings did not impress me at all.
