Thanks alot for your help guys!
We have an apartment now, which we managed to rent from a family in New Paltz, so that is taken care of. Our only problem is now that my girlfriend hasn't found a job yet, so I am hoping she will get one soon.
But besides all the practical arrangements, I am excited to see how's New Paltz. I've heard a lot of good things about it, so I don't think it will be a problem. Plus the hippie surroundings may jus tbe fun

. I have prepared myself for living in a totally different kind of place than Finland, so I have an open mind.
I am a little nerovus to see the level of the university and how will I manage with studying in English. I mean I have been dating an american for 3,5 years and the language in general isn't a problem. But the academic language is something to get used to I guess..
Anyways, I just wanted to to thank you for all the information, it was very helpful.
