Of course, if you have dual citizenship and speak the language, it makes sense to look up Smatsa Aviation Academy.
As regards courses prices, they are indeed very competitive, but not unusual in Central Europe; a quick search found these large FTOs in Poland and the Czech Republic, which offer comparable rates:
fATPL ALL-INCLUSIVE - Fly in Poland - Fly in Poland
Flying Academy - Zero to ATPL
I completely agree with the above advice to go and visit the FTO before commiting tens of thousands of Euros. The extra travel expense is priceless compared to what you can actually learn by getting there yourself - and asking the right questions.
However, in this industry you'll be lucky to be able to predict what will happen in the next 10 months, let alone 10 years...
