My favorite cities (the ones I've visited once or more times) are :
- Prague, because of its history, ambiance and beer.
- Vienna, because of its history, ambiance and sachertorte/coffee/hot chocolate.
- Imst, because of the wonderful alpine landscapes of Tyrol.
- Geneva, because of its history, ambiance and lake (+ great watches).
- Firenze and Pisa, because of their history, ambiance and pizzas (+ pastas).
- Marseille, because of its history, ambiance and bouillabaisse.
And some others that are less famous and that are related to my own family history.
