Just to give an idea of where Tallinn, Estonia ranks on this list...
- One of the most "connected" cities in the world.
- Pickpockets and occasional drunk brits/russians on holiday getting into fights. Otherwise far safer than most US cities.
- 50%+ speak conversational English.
- Decent to nice places in the most expensive part of town ~$500-1000/month You can go balls out and get a pimp place with a jacuzzi tub and it's own SAUNA for $1800-$2000
- Highest per capita instance of supermodels in all of Europe (actual stat, no joke)
- Beer or shot around $3 at bar
So, other than rent being a bit high (still far lower than Austin prices) it is looking pretty good.
