very well organized, map explains everything, what I like the most is the app, not only using it for the audio guide, but also it shows the painting photo along in high detailed resolution
you can download it for free before coming to the museum.
as for the paintings, they cover a little bit of everything as genres.
if you are into impressionism, don't leave it till the end (the way I did) just start with it, because it would be in the last rooms of the journey
