Things we love:

Freewave wifi hotspots all over the city, no password required. Vienna loves bikes. It'd be hard to find a more cycle friendly city, there is no shortage of dedicated paths, parking and bikers. The Daniel Hotel, with its rooftop bees, rentable Vespas and killer bar. 'Gemütlichkeit', the kicked back, relaxed culture you'll find in the traditional coffee houses. Its home to the world’s oldest zoo.

Things we wish we'd known:

They must like their Sunday sleep-ins, nothing is open. Most bars don't open until late, always check. How good Vienna coffee tastes. The trams are both easy and convenient. Naschmarkt, an eating, drinking, socialising extravaganza isn't open on Sundays, damn.
