Modern and clean unit with beautiful views of the mountains including Mount John (observatory) and great for stargazing on clear skies which thankfully was the case during our stay. Great location with short drive to the village and Lake Tekapo, and launching pad for activities at Mount Cook.
There were some items which didn't match expectations and photos. Telescope doesn't work in Unit 2 and was advised it was the same in Unit 3. There's also no outdoor furniture in Unit 2 (or Unit 1). Looks like it's only for Unit 3 from what we observed.
In summer it can get pretty hot in the unit when you return from a long day. You can open the windows but insects including mosquitoes can come into the unit despite best endeavours because of the close proximity to the pond.
