We had a great time staying in Adam's place while we were in Te Anau (we actually stayed at his twice - before and after we completed the nearby Kepler Track).
The standalone unit is incredibly comfortable and Adam went above-and-beyond to make us feel at home (there were fruits, candy, and other treats available upon arrival, which quickly made us feel welcomed). The home has a great bathroom and small kitchen and is located a quick 10 minute walk away from Te Anau's main shopping/restaurant strip.
Adam is also a fantastic host. He met us with a smile on his face, asked about our trip, and offered advice on the area. You can tell he genuinely cares about his guests and we were very lucky to meet him. We would highly recommend Adam's place for anyone venturing to Te Anau.
