Darren and Lynette's house was fantastic. We are a family of 5 adults and there was plenty of room with the 2 living rooms and 2 bathrooms. The house was absolutely spotless and had everything you could need. Kitchen was well equipped and the house had lots of great additions like the bikes. Was cold during our stay but heating was amazing with 2 fireplaces, several heaters and electric blankets.
We had a jam packed couple of days with tours so regretfully we didn't get to spend a lot of time in the house. My advice would be that you need at least 3 nights to really experience all that Te Anau, Fiordland National Park (and Darryn and Lynette's house!) has to offer.
