Quality of life varies greatly between countries.

That said I would certainly consider Bratislava if I was moving East. Its proximity to Austria (Vienna in particular) means that you can, in many ways, have the best of both worlds.

I think in most capitals I've seen quality of life isn't that much worse, don't get me wrong it's not really on the same level as Paris or London (rural areas on the other hand - just don't make any random country trips on your own), but at the same time it's not like moving to Syria or something like that - for example I find Vienna to be quite unsafe and unappealing, compared to say Zagreb (related to that I actually know a guy who commutes from Bratislava to Vienna for work - the rent difference alone covers the commute).

It depends on what you want, but you can actually compete for staff even if you have < million € in seed capital, rent and office space is cheap, etc. if your goal is to bootstrap your company then moving to Eastern Europe can help you with that.
