We booked this place for its location as a convenient overnight stop on a drive up to Abel Tasman NP following the Transalpine train from Christchurch earlier in the day. It is located on a beautiful spot overlooking the lower Buller River gorge. The cafe/restaurant served good food and drinks at great prices and hospitality could not be faulted.
The rooms are really for backpackers (bunk-beds and a single for the three of us), are small and of course there are shared wash/toilet facilities. If you're ok with that, then the location, eating breakfast overlooking the river will be your reward.
Bring insect repellent unless you are happy for the ubiquitous sandflies to enjoy eating you for breakfast (lunch, dinner or indeed anytime).
