Questions from foreigner :)

[AlfaQuarto]

Hi Everyone

I know that this site is mainly about architecure and communication but I've got some general questions about living in Denmark

Let's start with some introduction

I'm IT student at Technical University of Lodz, Poland and I would come to your country on my ERASMUS exchange for the spring semester of academic year 2011/2012. I want to enhance my IT knowledge and skills at DTU in Lyngby (as I find out it is the city near Copenhagen).

And now my questions connected with my trip to your country

As you may suppose in Poland we do not have many banks from Denmark. However I need to have a bank account in some bank (I'm thinking about Nordea) which have branches/ATMs in Lyngby. So I want to ask you which bank is the most popular in Danmark and where can I find some info about their ATMs (if it would be Nordea, does it have many ATMs/branches in Lyngby and Copenhagen)?
Next question is about flats , because I'm thinking about renting (together with my two friends) some flat during my residence in Denmark How much (approximately) would it cost? Do you know any real estate agency which would be able to help me find one?
And in the end I want to know how much costs the communication?

That's all Thanks for your attention and sorry for mess and mistakes in text
