I found this Global liveability report today.
Apparently Melbourne is the second best city in the world to live in. Congratulations to everyone who lives in Melbourne!
But of course (in my opinion) Hobart is a much better place to live than Melbourne. Which (logically) means that Hobart is actually the best place to live in the world.
(I couldn't find Jelenia Góra on the list, but apparently Warsaw is about half-way down the list)
