Hello! Croatian girl will cycle Wien -> Bratislava

Hello cycle friends!

I am Alma, a Croatian girl who likes to cycle. I would like to cycle from Wien to Bratislava this summer. Can anyone tell me where I can find a good map for this journey? Is there maybe one online?

Also, is there any special information I should know about this journey?

Thank you!
