Artist/Prince Eugen gave the building and his collection to the nation. I'm not sure I could give the full three thumbs if it were not for the fabulous location. Djurgarden really does draw residents for picnics. get a 47 bus if you must but it's a wonderful walk. pass Skansen [qv] on your left and go until the road does a rightangle turn left following the coast. There you wil find the museum.
