The house is new, modern, and an overall nice place to stay for a stop in Lake Tekapo. We found the two decks very nice relax on and view the lake and the wonderful NZ sunsets. The kitchen was nicely stocked and the BBQ grill was nice to have. The washer and dryer came in handy too. The house was in walking distance to the town center.
I was not aware that the house was semi-detached with another rental space. It was a little confusing when checking in as this is not explained in the listing. The only annoyance was the main door slamming at random hours when the next-door guests were coming and going.
The neighborhood seemed to consist of mostly Airbnb style rentals for travelers and places to crash while passing through the town. Which isn't bad, just an observation if you're curious about the area.
