Hangzhou is a nice city.  It's different than Beijing, a little warmer, and cleaner and more friendly.   I live in the sprawling suburbs where every building seems less than 10 years old.  
It's so much cheaper than Beijing. My biggest expenses is food because my company pays for my housing.  Food is almost half the cost as Beijing.  The downside there aren't as many nice shopping malls and Starbucks near me. But they're only a 15 minute bus ride away, so it's not so bad.   My apartment is nice so I can't complain about that.  Also there aren't any foreigners living out here.  Here's a video of me going into Hangzhou city.  Peace.
