Even better than expected, the walk up to the hut gets you a little puffed but it is well worth it. We were a little concerned about the small space and semi-outdoor amenities due to our extended 8-day stay in the hut, but in the end it was a fantastic experience.
It's also in a great location, a very short drive from all shops you may need (takeaway, supermarket, bakery etc), not far from Christchurch CBD and only 80 minutes drive from major mountains!
