This post is based on an email of advice I sent to my friend (and future flatmate!) David when he decided to move to Zürich from London. I think I did quite a good job, so I'm posting it here in case it's useful to others. Prices are given in Swiss francs and converted approximately into pounds sterling according to the current exchange rate. Come to Zürich! I probably won't move in with you, but I will make you dinner.
