Hilton Vienna

Vienna's main branch of the Hilton stands just on the fringe of the Stadtpark, one of the city's leafiest spots. This could come in handy if you're preparing for a ball-busting conference - a stroll in the park after breakfast is sure to set you right (and if everything goes horribly wrong later, the birdies and squirrels are sure to offer kind words of consolation). Back in the hotel, you'll find all the business essentials, including video conferencing and secretarial services. Book in advance and you should be able to secure views over the Old City - a prospect that's well worth waking up to.
