Continuity mistake: When Bond arrives at Tiffany's home in Amsterdam, he rings her doorbell. It's shown that she's living on the 4th floor (T. Case), but through the speaker-system she tells Bond to come upstairs to the 3rd floor.
Suggested correction: Although her outside indicator does say "4", it's possible that unit 4 could be located on the 3rd floor.
What we in the US call the second floor is the first floor in Europe. So a US fourth floor is a European third floor.
Definitely not everywhere in Europe. In the Nordic countries, for example, the first floor's the first floor.
True, but this scene takes place in the Netherlands where floors are numbered Ground, First, Second etc. So, not a Nordic country.
