Which cities have you seen those 200 €/month apartments in? When I was studying in Joensuu (a city of ~75k), a 25-30 m^2 apartment there cost around 500-550 €/month (unless you're lucky enough to get one of few student apartments from the city). I'm a bit skeptical that you can get a (non-subsidized) place for 200 € in a city, and having to have a car will bring the cost up anyway if you move to the country (good luck finding work without having to commute to the city).
