Ok, this answer is for AlfaGTV,volkoff and other guys.
The museum is open avery day, from Monday to Friday. This is opening hours: 10:00-12:00 and 14:30-17:00
They are always all very nice with people, fans and tourist
But if you come from afar is always better to ask, I would not like that you came and for some reason the museum was closed!
So, here e-mail of museum:
