Christian was a gracious and thoughtful host, with fantastic taste in music and an impeccably appointed apartment. It was very comfortable with a splendid bathroom and shower. He generously gave me use of the kitchen and helped me out downloading and printing the schedule for getting to the airport by U-bahn and train which saved a fair deal of euros. Mexikoplatz gives a different flavour of Vienna as it is working class and ethnically diverse, and there is a brilliant green grocer at the entrance to the Ubahn where they fresh squeeze and bottle juice super cheap.
