Absolutely impressive! Make sure to select what you want to see because (at least in our case) one day was not enough for us to see the whole museum.
The Egyptian and the Polynesian exhibitions are particularly great in terms of museography and of the items they hold. It feels a bit wrong that they are so far from the countries they belong to, but at least they are well preserved and can be appreciated by the visitors.
It is more of a mix between a natural history museum and an ethnographic museum, because it has areas dedicated to cultures from around the world.
We also visited the temporary exhibition on Cats and Felines. It was good overall though I think it should make more emphasis on important topics like environmental issues and conservation efforts, instead of making the conclusion about “sharing funny pictures of your pets”. Makes it seem childish and unimportant —which it’s not.
The lockers have an additional charge, but at least they are affordable and easy to use. They should be included within the fare in my opinion, because (at least in winter) they are a necessity, not a luxury.
The restrooms are clean and the staff is kind. The shop has interesting items but is ridiculously overpriced, so don’t even bother.
In conclusion, this museums makes for a whole day visit, and is really worth it.
