If you like beer, then it is good, since beer there is not that expensive.  So that is why pretty much everyone drinks beer.
If you need washroom while you are walking around, good luck, since they will charge you to go to a nice washroom.  If not, you can do it on the street, no one will say anything.
As for accomoration, it depends on where you want to stay.  There are some hostles where it is around $50US per night, which is not bad.
Good luck la.

Oh I forgot.  If you are planning on staying there for 30 days, It will cost you some 5000Euro.  But you can ask for some part time job to help out.
Good luck
