If you’re planning on staying in Te Anau, Doug and Sharyn’s place is worth scheduling your trip around. The house is immaculate and has everything you could ever want in a lake house (fireplace, huge picturesque windows, heated tiles in bathrooms AND the kitchen for cold mornings). It also is, for my money, the best view in Te Anau with an unimpeded look at the lake and multiple peaks surrounding. It also makes for a great jumping off point to get to Milford Sound (which I would also highly recommend).
Long story short, book this place and don’t bother looking at other accommodations. This is the one you want.
