Riverview Collingwood is everything you are looking for in an Airbnb: It's really clean, tasteful and John and his family are very welcoming and respectful. He even shared some of his fresh catch with is, which we used for a nice barbecue dinner in the beautiful garden. The view onto the garden is stunning, and having a barbecue at sunset is an absolute treat.
The location of the Airbnb is very good if you want to explore the regions between Abel Tasman and Cape Farewell. Just as a note and not a negative: the WiFi connection is pretty weak, so if you are needing a strong WiFi it might be a problem. We didn't, and thus I would say that Riverview was an all around perfect stay for us.
