It's cheaper than Italy or other West EU countries. Ljubljana (especially center) and tourist hotspots have of course a bit inflated prices, but elsewhere if you have a monthly salary 1500 eur or more you can live a good middle class lifestyle.
Two weeks is plenty; you can visit the must-sees (Postojna cave, Bled, Piran, maybe some rafting in Soca river) and spend a week in Ljubljana, depending on what you like. Ljubljana is at the center of Slovenia so it's a good spot to drive anywhere with a car for one day visits, although roads can be crowded in the summer because of all the tourists (many headed to Croatia seaside).
If you are into festivals, during the summer you have several in Tolmin (by Soca river, near Italy) and a good one is "Pivo in cvetje" (beer and flowers) that Roosh mentioned, it's in July in Lasko town (good for hunting Slovenian girls as Ljubljana is filled with foreigners during the summer when university closes).
