In German, numbers are spoken from left to right, as in English, but ones and tens are always swapped. So 23 becomes three, twenty, and 135 becomes one hundred, five, and thirty:

Achter Stock (8)
Achtzehnter Stock (18)
Achtundzwanzigster Stock (28)
Dreizehnter Stock (13)
Dreiundzwanzigster Stock (23)
Dritter Stock (3)
Einundzwanzigster Stock (21)
Elfter Stock (11)
Erdgeschoss (0)
Erster Stock (1)
...

Oh, and the first floor is called the ground floor and is not counted.

The UK also has the off-by-one floor numbering.

Also a nursery rhyme with the line "four and twenty blackbirds"!

That is only one and ten blackbirds.

There are probably some that you can't see.
