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.
