This, absolutely. Was there with my other half in August last year and it was beautiful. Not exactly thrilling night life but plenty to see in terms of countryside and culture. Accommodation is cheap, too.
Probably worth hiring a car for as things are fairly spread out, but the bus and train system is pretty good, trains especially. The train ride from Ljubljana is incredible.
Food is mixed, don't expect anything too fancy, but there are nice places in town. Garlic soup was a regular fixture.
Worth spending a night or two in Ljubljana too, actually. There are some awesome restaurants and jazz clubs and it's beautiful city generally. Nice folk.
