So the coopculture.com website states in english:
"It is confirmed the prohibition of bringing backpacks, camping , bulky bags and luggage / trolley, can be introduced medium and small size backpacks to shoulder, which must be checked, as any other bag, with metal detectors, opened and visually inspected by the Urbe Security Institute, responsible for the entrance inspection."

I understand that large backpacks aren't allowed BUT does the statement "can be introduced medium and small size backpacks" mean an average sized backpack IS allowed? I'm wondering if it's just a matter of Google not translating correctly and inserting the word "Introduced" as meaning can be brought in or allowed. Also, is there a place to leave my backpack during the tour IF it is indeed not allowed or too big?
These may be stupid questions so bear with me as it is only 6 days until my first European solo trip/first time to Europe and the nerves are attacking my common sense. 😔
