We visited this museum just because it was at midway on our long distance drive that day and was perfect spot to rest. It turned out to be one of the best museums we ever visited.
It is not a big museum as the popular ones in the country. However it has a nice collection of things, the variety of which was quite a lot to facinate, but not too much as in the big museums to overwhelm. The natural history collection had many bird, mammal and skeleton samples. There is also a collection of skulls of other human species like neanderthals, etc. In addition, there is a nice minerals collection.
The second floor was reserved for modern art exhibitions, but I cannot comment as we are not fond of modern art.
Parking: there are two big underground parking just under the museum and under the square across the museum. Therefore, access by car is very easy. The price of parking was okay or as one would expect considering it was the most central location in the city.
We bought the ticket when we arrive. There was not a queue, however it was a low season. Ticket can also be bought online. The price of the museum is 6 euro per person.
Overall, it was a quite nice experience for 3 hours that we spent.
