Excellent!
Sarah is very friendly and helpful during our stay. She made sure everything is ok during our check in, introduced us to her partner and friendly dogs. She even reminded us to put our shoes inside since it was going to rain :)
The unit is clean and tidy, with a very comfortable bed (plus a cool window above for stargazing), and exceptional shower. Breakfast was more than enough. We will definitely come back if we have another chance to visit Arrowtown/Queenstown.
