We had a fantastic 3 night stay at Mary's place in Manapouri. It was super clean, comfortable and very homely.
It is a perfect location for the Doubtful Sound boat trip (Pearl Harbour is a 5 minute walk away) exploring the Kepler track and a 15 minute drive to the bigger town of Te Anau (where there were some great food options, bars and the Glowworms).
A great space in a beautiful part of the world. Would highly recommend and would love to return again one day.
