Don't know a specific list, but you may want to take a look at Cluj-Napoca. A few guys from here put together a site, more or less as a BREXIT joke: http://www.transylvaniabeyond.com/welcome#move-to-transylvan.... A bit commercial, but not very far away from the truth. I've lived here for my entire life, but traveled a lot as well (Europe & US) and so far I haven't found another place I'd switch to.
