We were looking for a place outside of Wanaka with panoramic views over the mountains. We couldn't have found a better place. The house feels and looks luxurious. The views are impressive, both during the day as well as at night (beautiful starry skies).
The furniture is comfortable, the kitchen is very well designed, and it had everything we needed for comfortable cooking. We felt like at home and loved the privacy and quietness the house offered. There were plenty of towels, blankets, and electric radiators.
The drive to Wanaka takes about 25 minutes. The house is located on a hill, at an elevation of about 500 meters (so it's slightly cooler than in Wanaka).
As for improvements, I would replace the router with a new one that offers better signal throughout the house. The signal was only strong in the living room (and barely worked outside of it). The speed was fine (30 mbps download) but not "high speed" as mentioned in the listing.
Still, one of the best Airbnbs I've been to.
