My top three experiences while travelling consist of:
3: The efficiency of public transportation in Vienna. I live near Turin. Turin has only one subway line while the transportation by bus must be increased. Vienna has 7 subways lines that are always clean, in time and safe.
2: I always had the thought that the Austrians are quite cold but during my journeys in Vienna I experienced the opposite. I had the lucky to meet always people that were so kind, friendly and helpful. They also have respects the rules and public spaces (public space which are always clean).
1: the sensation of being home in that town and the love for the city (I experienced that feeling both in Vienna, Florence and Lucca).
