Aunties is a brilliant base - so comfy, and so warm.
Beware your knees on the walk down to town, and catch the bus / taxi back up! The buses are regular, and close - get yourself a Go Card and save a whack on the onboard cost.
Roslyn town is lovely, the supermarket provides what you need, and the Luna hotel serves fabulous meals and a delightful view over Dunedin.
If you're cooking, all the basics (salt, pepper, oil) are available, as well as the 'nice-to-haves' such as a touch of cinnamon, nutmeg, or a dried herb or two. Knives are sharp, and the pots & pans are plentiful.
Next time, we'd visit here again in a heartbeat!
