I absolutely love everything about the city Zürich!
I find it to give me many opportunities, it is not big, but it is big enough to live " big city life". It has perfect public transport, it has perfect night-life, it offers perfect shopping opportunities - for poor people and for (too) rich people. It has really great view, houses look really nice (like everywhere in switzerland!). I mean, I have not traveled so much, and I am young. But compare to Estonia, the capital city Tallinn, Zürich offers much more and people are more happy here! I am more happy here
But of course, how many people we have in the world, that many different opinions there are!
