Romantic European winter getaways

Hi y'all,



I was thinking of planning a romantic few days away somewhere in Europe for the wife and I. The only problem is we'll be visiting in early Jan 2015 so likely to be cold. We've done Paris in the winter before but was thinking of somewhere else. Salzberg, Austria randomly came to mind. Can anyone recommend any of Europe's other city's/towns for romantic winter getaways?



Thanks!
