I was fortunate to be offered an overnight trip to Vienna to give a presentation at a small conference and flew from Amsterdam to Vienna on 6 May 2017 and back on 7 May. You can read about that here:

Luckily I had some time to take a look around this beautiful city. I’d recommend getting a Vienna Pass,which is a tourist pass you can buy for 1, 2, 3 or 6 days. It then gives free or discounted entry to all the main attractions. There is extensive online information in English at www.vienna.info to plan your trip.
I stayed at the beautiful Parkhotel Schönbrunn.
