‘vis-à-vis’ is more about two things, the meaning is very similar to ‘par rapport’ but is more used for confrontation between two things:

"With regard to the issue of the depreciation of the euro against the dollar raised by the other interested party, it was […]"
Here ‘vis-à-vis’ confronts the Euro and the Dollar but ‘Par rapport’ could have been used too.

un appartement sans vis-à-vis
