A few flights up, the 5th floor is filled with Impressionism. Before I forget, one interesting detail about the day was everyone, something like 90% of visitors, were French. Obviously Americans travel all over the country and go to museums, I'm doing DC this summer, but I found it interesting that it was probably 90% French, 9% Asian (must have been a Korean bus tour) and 1% everyone else. Only heard English by a group of 5 women, one woman who was clearly a professional art historian, leading them around.
Another thing, this was a Tuesday at the end of February. Not a lot of international tourists. Museum filled up pretty well during the day. Again, if you go to France and don't want a typical American experience (you would have to hold a gun to my head to take a tasting tour), go slightly off season. Fewer tourists means better access to everything.
The 5th floor was staggering in it's beauty and depth.
