My wife and I stayed at the loft for one night during a road trip through Mew Zealand. The loft definitely made our experience in Arthur's Pass a good one. It has an awesome location close to Arthur's Pass. The property was clean and had all the amenities needed. There was a small heater that kept is warm during the night and the kitchen had everything needed. The owner communicated quickly and left detailed instructions in the loft before leaving.
Although there is no cell reception or wifi, there is a small motel across the street that will give you wifi access if you ask nicely. However we found it nice to be disconnected for a bit. The motel also has a small bar and restaurant which was convenient.
Would definitely recommend staying here for a visit to Arthur's Pass!
