We both hadn't been to Vienna in many years, and when our friend invited us to her birthday celebrations in her home town we happily accepted. We made a short trip out of this and combined the birthday party with some sightseeing and exploring which I am now sharing with you. Vienna is an easy destination from many European cities and from Berlin, we flew there in just one hour with AirBerlin. The airport in Vienna is big and modern and convenient and is perfectly connected to the city. We bought tickets for the CAT train which brings you to the city center nonstop in 16 minutes. Once you arrive, you can easily connect to your next stop in Vienna. Great and easy start, do read on for more on what we got up to and our personal recommendations!
