I went to Wanaka in April 2018 and stayed at Aspiring Lodge Motel for 4 days. We went at a time when the temperature has started dropping and the constant winds have a chill to them.
The room we were in was surprisingly warm - did not even need to use the heater! The King bed (or was it super king?) was comfortable. The shower pressure was slightly low (what my partner says) but I found it find; as long as hot water comes on pretty instant, I'm satisfied.
There was also a hair dryer handy and a small kitchenette. Our room did not have a stove but we made do with a microwave and plus you do want to eat out when you are on holiday. New World is conveniently stationed next door to the motel.
You cannot really beat the location. It is 2 minutes walk to the lake, restaurants and shops. I would definitely stay here again!
