We stayed at the place for 5 nights (9 adults + 2 babies).
Location: Overall, we enjoyed the location. Pretty secluded, the bach has to offer New World just 5 min drive away and Napier- 30 min. Car is a must. Have no idea how public transport works in the area.
The house is situated on the owner's land. So, the owner's house is just some meters away.
Communication: Communication was great. The owner and his grown up children paid us visits every day (sometimes even twice a day). Ben himself was really fast to help with some issues we had such as power loss.
The house: Overall, the bach is nice (fireplace is the best), though a bit aged. Therefore some renovations are needed (one of the bathrooms offers only hot water, so no showers can be taken in there, squeaky floors). Cockroaches were seen in the bedrooms. Ensuite in the master bedroom has blinds which are completely see-through at night. So, be aware of that and before going to a shower in the evening - do something with the windows. We had to use towels to cover them.
To sum up, we recommend this place to people who prefer quiet and relax holidays.
