Public Question Asked by flavia about Dusseldorf

Hi I wish to know how much it cost to take a taxi from dusseldorf airport to goethe institut

I know that it isn't so far but here in Italy it cost very much to pay from the airport...and then I want to make another question does it cost more if I call a taxi from my hotel?even if I have to go to a place close to this..?Thank you for your future answer...
