I was thinking about those white ghost chairs [houzz=] And what do you thinbk about the cabinet on the right? I am thinking about getting something in a whiter color and a bit higher?

Hmmm that would depend on the size of your chandelier and the size of your table and the height of your room/table as well. Also the height of the people in your household. Usually i would say aim that your chandelier is less than half the size of your table. If it is bigger hand it up higher. Else something about 90 to 110cm or 30 to 35 inches above the surface of your table.

Dwell ( and others ) do coffee tables that then raise to be dining tables.... team this with a couple of folding chairs that you can hang on hooks when they aren't in use - and you keep the space uncluttered... maybe worth a look ?!

Dining table at the kitchen side of the living room perhaps ?
