Haha, this caught my eye 'cos I'm originally from Finland. I haven't myself thought of going to uni in Finland, it just doesn't interest me whatsoever. No other reason than that. I love Finland and from what I've heard the schools are decent. Like someone just said Sweden and stuff might have better established universities and the uni's in Finland aren't so high in the rankings, but if you're looking for a cheap enough education, Finland is a place to look into
Obviously seeing that you are an EU student.
If you're worried about the language barrier, so many people there speak fluent English these days it wouldn't be a problem I'm sure. A lot of the uni's offer courses and degrees in English too. I know a good few people who have moved over with no Finnish at all and are doing just fine. I'm sure you'd do grand in the bigger cities, at least.
Like someone said earlier, the housing and public transport is amazing. Even though it might be -20 outside, you'll definitely be warm in your home. They have all that insulation stuff and proper windows, unlike in Ireland haha. Over all, the standard of living is so much better over there. Don't get me wrong, I like Ireland, even though it has its flaws.
