Bad experience. We arrived there, we are tourists so OBVIOUSLY we don't know how it works, we ask for tickets and the "smart guy" with few hair and glasses at the reception asked us if we have reservation, we say we don't have and we didn't know we needed it and he says "well no reservation no enter" and "now you know!" with a very aggressive and "smart" tone, as if we as tourists should know everything about your museum as if it's some holy place. It would have been fine if he said that with a normal tone and not trying to be the smart guy. Then the guy realised he wasn't being funny and he said something "I'm just joking, here is how you can book it" but at that point we didn't care anymore. Learn how to treat tourists otherwise your country will never attract more
