Moving to Oslo

Hello everybody, I will move to Norway next year (Oslo). I have many questions in my head regarding Norway but do not know from where to start! I am already having some lessons in Norwegian language. Of course, I will contact the Norwegian embassy here in Athens to get the main information about Norway… but I would appreciate you, guys, who live there, give me some info about how life is there, how to find a flat (a nice location in town) and how to rent one (what are the documents needed), the daily life cost, the climate, etc…. I don’t know. Sure I will have more questions as soon I receive the first info from you. I am planning to make a first trip to Oslo next year (March or April) to get a first idea of the country… hope to meet you there at an Internations meeting, then… Thanx, Irena.
