Sarah's house is absolutely gorgeous, very spaciously furnished and equipped for living easily. It has a good internet speed. The TV is equipped with Apple TV and Netflix, so it is possible to watch popular movies, and also bluetooth from a phone or computer to watch sports or other services. We spent four winter nights there, and were warm with the heaters on, and plenty of blankets.
The master bedroom is a very large suite upstairs, and there are two nice sized bedrooms on the main level. Upstairs and downstairs bathrooms. Entry is through the laundry and shoes need to be taken off in the laundry room. The house has a bit of a Scandinavian feel.
The house location is about a 15 minute walk to town centre, but we only drove because the temperature was very cold during our visit. It is possible to walk to the lake a few streets along.
It is a great place to explore around the area. We spent one day cruising on Doubtful Sound, another day hiking parts of Kepler Track, and another driving to Milford Sound to look at scenery and do short hikes. Saw wekas in the carparks at Milford Sound, and a kea while waiting for the Homer Tunnel traffic light to change.
