My Dad and I just spent 3 nights staying at Stephens place. We could not recommend it highly enough. Stephen is an excellent host with super fast communication and check in was a breeze. The location is excellent with only a short drive from the airport, walking distance from a good New World supermarket and a short drive to gas stations and liquor stores (they dont sell beer & wine in supermarkets in Invercargill).
We were particularly impressed with the cleanliness of the place and the high quality appliances to use. It was super warm and really quiet at night for an excellent nights sleep. We loved having the full Sky options for our entertainment as well. Other positives included great shower pressure and comfy beds. All and all just a great place to base yourself for your Invercargill adventure.
