Megan's studio in Wanaka was perfect for us - it was close enough to walk into the town centre of a morning for breakfast and was warm & cosy at night. Parking was easy and the kitchen was well appointed so we cooked dinner most nights.
While there was no washing machine, a drying rack was provided so I was able to hand wash and leave to dry overnight. The courtyard at the front gets lots of sun & would be great during spring & summer!
There were two cats (from next door, maybe?) that kept trying to get inside - we're not really 'cat-people' so it was mildly irritating after 4 days, but they seemed friendly enough.
The only downside was the wifi - we had a lot of trouble connecting to the device even after making a special trip to Vodafone to troubleshoot the problem. Even though we'd topped up the account and not been able to use any of the 5GB, Vodafone wouldn't refund it to us - goodbye $50! There is free wifi in the Wanaka town centre (which we realised after the fact) so I'd suggest you just use that.
