Tei's place is fantastic. It's true to the photos and is a great place to relax in. The bed is comfy, the bathroom is probably the best I've seen in an Airbnb and the detail Tei has put in to providing the home away from home vibe is to be commended.
Bring your own food (milk, coffee, tea and some snacks/breakfast makings were already available), or there is a Woolies two minutes away or an IGA on the main street (both walkable). The kitchen has an airfryer, microwave, toaster, fridge, toasted sandwich maker etc, so plenty of chances to make your own meals.
The 'unit' is attached to her main house, but there's definitely privacy and I liked knowing I could contact her if needed, but enjoying my own space at the same time.
Smithon itself is a handy starting point for the Tarkine drive and also has easy access back to the main road back to Devonport etc.
