As much as I hated living in Sweden, I'd recommend it on the basis that Scandinavians on the whole are very good at speaking English, probably best out of all European countries, except of course the UK and very possibly the Netherlands too. Also, they like to drink and party, especially university students - if you're looking for a drug-friendly culture I'd go elsewhere though because drug use is looked down upon by most people (at least compared to other countries I've been to), and although a fair amount of young people take drugs they tend to keep it very hush-hush. Also... you said you wanted to get laid. Well Swedish girls are very forward, in fact so much so that most of the guys there are lazy bastards that let the girls do all the work and they don't even know how to approach girls properly

(thank God I left that place). And Swedish people are quite good-looking and very slutty.
Oh, and all education is free there, so no expensive tuition fees. I think that applies for foreigners too although I'm not 100% sure. Also Sweden is very clean.
Negative parts: Not drug-friendly, expensive alcohol, the music people listen to in mainstream clubs is appalling, people can be very reserved and aren't that easy to get to know (although it gets better if you go to one of the major cities like Stockholm, Göteborg, Malmö, or even one of the major university cities like Lund, where I studied. I'd recommend all four), winters are long, and people are often miserable and depressed - Sweden has a very high suicide rate.
Personally, even though I've only been to Holland once it seems like a nice place to study, I have a Dutch ex who studies in Amsterdam and he's having a really good time. But I love London, so no chance of me moving anywhere else until I finish my studies, except maybe spending a summer in France improving my French.
Anyone study abroad in Denmark? I'm looking at a program in the Copenhagen Business School in Denmark with an exchange program for the summer.
Never lived there, but I've been to Copenhagen quite a few times and it's a really nice city. I'd imagine that the culture and everything would be quite similar to Sweden though.
Krakow, Poland....
The reason why these two countries...simply very cheap and HOT women of course not to mention awesome food, DUH!?!?!
I've only been there once, but I wouldn't move there simply because it seems it would be difficult to get by on just English, and Polish is very very difficult to learn. My boyfriend is Polish and I'm trying to learn the basics so I can communicate with his non-English speaking family next time I go there. And it's fuuuuucking difficult - and I'm not bad at languages, I'm fluent in English and Swedish and my French is rusty but decent, but I still find Polish so hard to learn because it's different from the languages I know. If you're going to learn another language make it one which is close to English (ie shares a lot of words) like Spanish or French or something.
Also, according to my boyfriend Polish girls are quite hard to get. He says the ones that go abroad become quite slutty but the ones living in Poland generally have a reputation for being a bit difficult.
