We stayed here for 2 nights and liked it a lot!The rooms are very convenient. There is a lot of space inside and also a nice place to sit outside (2 chairs and a table in front of each room). We also liked the kitchenette/living room area inside, where we could relax in the evening with other couple travelling with us.
There is also a shared laundry room available, but not free of charge (2 dollars for one washing as far as I remember).
We also loved the location - 10 minutes walk to Lake Wanaka (some relax on the beach recommended!) and around 10 minutes drive to Roys Peak Track (a must see!)
What we didn't like?
Free WiFi is provided but with transfer limit - I guess it was 0.5 GB or 1.0 GB per person for whole stay (we stayed 2 nights, perhaps the limits are higher for longer stay). This was enough for us, but I can imagine it might not be enough if you'd like to watch some movie on Netflix, share photos with family back home, etc.
