I would totally recommend Diane's house in Oban. Very comfortable and a lovely view over the harbour, very close to the main town area. It comes with its own aviary of wild birds ….. magical. Including the Kaka and Tui.
The photos don't do it justice so go see it for yourselves!
Stewart Island was amazing. Tropical but cold!!!
You need to spend at least four nights there to do all the walking tracks, try the local seafood and just chill!
