"A fiatal olasz nő az erkélyen főz."

Translation: The young Italian woman is cooking on the balcony.

Does the ending en mean on?

[Shamarth]

Yes. The possible forms of that suffix are: -n, -on, -en, -ön. Or alternatively, the suffix is -n, taking the appropriate link vowel ("o", "e" or "ö") if the noun ends in a consonant.
