The audiovisual history exhibition is interesting, and the building itself is absolutely worth a visit. There's also a great old-fashioned pharmacy and a shop that kids can play in and learn about history hands on.
In the basement you can also find an art workshop for children.
The rest of the villa is home for changing art exhibitions, and they are often very good. There's a lot more to see in here than you might first think.
The museum cafe is stylish, the small shop has a nice selection - and the service and the museum guides very friendly and knowledgeable.
A great visit any day.
