Wifi is NOT free. There is 30 min free (and an unknown amount of data, whichever comes first), then you have to pay. Other than that the kitchen is lacking in terms of pretty much everything. There is the basics (hot plate, pans), but almost no plates, no knives, etc.
Other than that (again, but this time positive) the place was very beautiful, there is a fast food restaurant on site with a great ambiance, the location is ok (~20 min from Wanaka), very clear view of the sky and its stars during the night…
The place to sleep itself was feeling old and not very well maintained, but it was enough for two night (it was clean and everything was working).
