"Η ευγένεια του."

[LenaKoutis]

Could this also be "his etiquette" ? I don't see myself talking about someone's politeness.

As an Eng. teacher I would "etiquette" in place of "politeness" because "etiquette" leans more to a formula of behavior rather than a feeling of kindness to another person.

Would 'his manners' work?

[jaye16]

Yes, it would and many thanks.

[spdl79]

Thanks Jaye!

As this word is followed by a possessive pronoun I think it should have a seond accent on the a but was told to watch my accents!

You are correct, it should have a second accent. It has not been possible to fix those yet, but rest assured, you know the rule!
