Te Anau is tucked up in the mountains of the Fiorldlands, meaning it's beautiful but semi isolated (as an area). The neighbourhood is very quiet and reminded me of staying up in a cabin in the woods, but located in the suburbs and conveniently close to town.
As advertised, there is no wifi at the space and even the one we rented with our car couldn't get signal. My friend also couldn't get data/signal. Come prepared with offline maps!
The space was quite cold in the mornings and evenings (during cold snap in May). There were space heaters in both bedrooms, as well as heated blankets, so sleeping was no problem. Both of us did end up walking around in double layers of socks and a sweater/hoodie. We moved a space heater to the main room for awhile and it helped a bit. I loved it; my friend who is from a much warmer climate had a harder time adjusting.
Check in was very easy. We cooked dinner in the kitchen, which had everything we needed, and used the washer without incident. My clothes weren't able to line dry over two days due to the cold, as an fyi (obviously not host's fault). Shower pressure was great.
We've stayed a handful of places over a couple weeks and this was one of the better. It had a lived in feel and was a very quick drive to town (not a bad walk either).
Highly recommend for anyone staying in the area (and you should definitely check out the caves while there)!
