Sarah and David's train carriage is just tremendous. We had made the long drive down the west coast from Abel Tasman to Greymouth, and arriving to such a set up was fantastic. Sarah and David have made so many thoughtful touches to the carriage and the area in which it is located is incredibly restful. We deliberately chose to stop in Greymouth en route to Christchurch in order to experience this unique Airbnb and we are so glad that we did. Couldn't recommend more highly!
