We were two families (group of four adults and two 12 year old girls) traveling to NZ from Australia and we spent in night (18 April 2019) at Justine's place in Wanaka.
The location is on a highway, so you won't miss it on Google maps. The house might appear old but is a very cosy place. It has Netflix for the children and the kitchen was very well equipped. Beds were well laid out. There are two bedrooms with a double bed each and one room with bunk beds.
The morning views from the balcony are as good as you can get from anywhere in Queenstown and we took heaps of pics.
The only slightly limitation is that the house has only one shower cum toilet and that did delay our getting ready in the morning. We did use the toilet downstairs in the laundry room. A second shower would greatly help.
Overall, a very convenient place in Wanaka, just 4 minutes drive from the Town Centre.
