If you want a romantic European city break but something a little different from much-lauded Paris, then the Austrian capital may just hit the spot. No better way to impress your other half than with a horse-drawn carriage sweeping past magnificent imperial buildings and storybook Hapsburg palaces, followed by an idyllic walk through Vienna Woods, where hearts and arrows are etched onto the bark of trees. And when it’s time to stop, the city is a haven of chandelier-lit coffee houses where the local speciality of sacher torte – rich chocolate cake with a thick, indulgent icing – is just the thing to share à deux. No matter that it may be cold in February; Viennese buildings are sumptuous on the inside and, besides, what better excuse to huddle up and keep warm.
