Where is good parking in Vienna?
If you plan to visit old city in Vienna, then better to leave your car outside it. Because it's almost impossible to find a free parking place in the city center, especially on weekends.
But do not be sad. There is good solution: "Park & Ride" garage parking. It's quite cheap (just for €3.4 for day) and located near the subway station
There are ten parking garages in Vienna, so you can choose closest to you or closest to city part that you want to visit: parkandride.at
