We stayed here for one night on a trip to Franz Josef glacier. The b&b is located about 30 minutes from
Franz Josef in a beautiful, secluded area outside of Whataroa. The views from the room are amazing, including seeing deer grazing in the fields.
The place itself is nice and clean, comfortable bed, nice warm shower and great continental breakfast.
However, because it is so secluded we were not able to get the WiFi to work the entire time, and the cell service was very sporadic. Make sure you make arrangements before traveling into the area on when you will arrive / where to go. While they sent us instructions day of, we could not get the message and were confused when we arrived. As well, the TV did not work in the room if you want to relax in the evening (there were not even batteries in the remote). Also note, there is no air conditioning so the room can get quite stuffy.
Accommodation in Franz Josef is hard to find so this is a solid option. Just be prepared to drive a lot as there is nothing nearby (restaurants, shops, gas, etc). We knew this going in, but it really is true!
