Amy is an excellent host and communicated well in advance. The house is a home away from home for us, had all the amenities (wifi, nice kitchen/pantry), clean rooms, comfortable beds and spotless bathrooms. The sunset in Twizel is beautiful - so is the dark sky, but we were there during full moon :( - and you can take all that in from the living room.
Amy provided a list of near by attractions and recommendations. The high Country Salmon and Lake Ruataniwha are minutes away from the house. Mount Cook and attractions in the vicinity are 60 minutes away by road. We spend an evening (6-9 PM) and the following morning (5-9 AM) to avoid the tourist and the buses. With a car, you can get to Lake Ohau and Pukaki, checkout the scenery and beauty of the region. Gliding and heli rides are two attractions you should try and they are better value and enjoyable compared to other major attractions. I highly recommend the place, an excellent alternative to Mt. Cook lodges and motels.
