I've been to Austria a few times, and I think any place that is outside of the bigger cities can get treacherous in winter. Especially those that lead up the mountains. My parents and I used to stay near a mountain called Wilder Kaiser (Wild Emperor). The nearest town to that is Ellmau. That would certainly work, but I'm sure Innsbruck fits the bill as well. I live in the Innsbrucker Street in my city, so that's a nice coincidence. :-)
