We stayed in Cardrona for the Wanaka challenge. Cardrona itself is not an exciting place to be but it was a good starting point for the surroundings. The apartment has enough cost space for 8 people to sleep in with two bathrooms. The terrace is quite small and there is no real space to play outside for the kids which was ok in our case. The apartment is very new and modern and has everything from dishwasher to coffee to puzzles to make you have a pleasant stay.
