If you like modern art and architecture, particularly Cubism, you will absolutely love this place. This would also be a good place for Frank Lloyd Wright fans, even though he had nothing to do with it. I feel like Wright's principles influenced this place (simplicity, no clutter, ample views of the outdoors, furnishings that harmonize well with the house, etc.).
But even if you're not so sure about modern art & arch., you'll probably like the F-M House anyway! It's so sunny, airy, bright, sleek and clean, sort of Art Deco-y. The grounds are nice, too. There are fascinating artistic details in the house everywhere you look (even down to the doorknobs, hinges, andirons), and the guides are excellent. The Frelinghuysen-Morrises had a wonderful combination of taste, artistic talent and MONEY. If you're familiar with the Gropius House in Lincoln, MA, the F-M House will probably remind you of it.
FYI, if standing for an hour or so is very hard for you, this tour may be a bit iffy. There are not a lot of places to sit in the house without your having to miss some aspects of the tour -- and there's a short flight of stairs to climb.
A final note: be aware that the F-M house is only open for a small part of the year. If you're in the Berkshires when it's open - GO!
