We stayed here for 3 nights as two adults couples. This is a great apartment just off the Main Street of Tanunda. It is well appointed and clean with access to a laundry and pool which is great. The kitchen was perfect for light dinners, after big lunches in the region.
Communication and checking in and out were easy.
The only thing I would say, is that for international travelers, the lack of free wifi ($10/day instead) may be a drawback. Being from Australia we could use our own internet, but it seems like something that could be easily fixed.
We would definitely stay again.
