Ive been living in Vienna since my early childhood days, since I was about 3 years old.
In short, Vienna has everything to offer.
Its one of the safest cities in the world, has a vast amount of cultural history with monuments, churches and historic places of interest throughout the whole city.
Walking at night has never been a problem for me personally - in all my time here. The club-scene is buzzing, the streets are rarely empty and we have everything to offer.
