Max's place is centrally located in Mount Victoria with great views of the harbour. It is high up the hill but an average level of fitness should get you up the steps to the house. The room itself was warm with the heater provided - but the rest of the house could get a bit cold. This is NZ though and this is to be expected at most places.
Max was very communicative but was unfortunately out of the country when I stayed. I was there for 2 weeks and so snags that came up were a little bit harder to resolve, however as I understand it Max is usually there with his guests so this is unlikely to be an issue for you.
