Und nichts von Leo -incl. der Fäden- passt??

This is an odd verb to use here..

I'm not sure which verb is odd here? The German seems OK. "Appears" is probably a bit strange though. Why not just say "The dining room looks ..." - that's what the German "wirken" means, surely? Or if you want to emphasize the "wirken" idea then try "the dining room makes a very ... impression." But I think maybe it would be better to try "The dining room is finely decorated and furnished" Noble is better for a person I think

'wirken' is not used often to mean "to appear" Although it can be used this way, it is more commonly used to mean "to work" "To seem/appear" is a secondary meaning.

It seems like a better verb would be erscheinen. (Das Esszimmer erscheint sehr edel.) In fact, many dictionaries (I think even LEO..) will suggest erscheinen as an alternative in this sense.

"Appears" is problematic here because it can mean, "den Anschein haben".
There is a differencen btwn.
The room appears luxurious.and
The room has a luxurious appearance.
(Luxurious is not meant to be a translation suggestion, just as an example)

@erl - posh wird eigentlich irgendwie augenzwinkend benutzt und hat einen wertenden Touch. :)

instead of noble

but not "appear"

suziq,

das Esszimmer wirkt sehr edel ist absolut Werbesprache, no German would use that in everyday language; so the language is posh, the word edel is posh, the whole sentence is posh!!

How about:

The dining room has a refined feel about it.
