Thanks for all the answers and tips! I'll go there today to look and knock on the wall. I'll also check with the board if they have blueprints that show whether the wall is load-bearing or not and if it contains any wiring. We've decided not to take the apartment if the wall is load-bearing because it becomes too expensive and cumbersome to remove. So I hope it isn't! What would it roughly cost to take it down if it isn't load-bearing? Does anyone have an idea? And what do you do if it contains electrical wiring? Then it becomes very expensive if you have to reroute them, I imagine?
There should be some electricity in the wall, but I don't think it needs to be that expensive, not in relation to the actual demolition of the wall. Maybe 3 - 5000.
I'm not sure, but you might also need the association's permission to take down non-load-bearing walls. It might be good to check that out before you buy. 
It's very likely that they have to give their permission. You don't actually own the apartment, just the right to live there.Mikael_L said:I'm not sure, but you might need the association's permission to take down non-load-bearing walls too. It might be good to check before you buy.
The wall is not load-bearing! We have checked now and according to the current owner, it is not load-bearing, and apparently, two neighbors with similar apartments have done exactly the same thing we planned and removed that specific wall. Even those who live there now had considered doing the same. So now we are very happy but wonder how to proceed. We don't dare to do it ourselves since we have zero experience with renovation. So who should we hire? A carpenter? There was an electrical outlet in the wall, how do you reroute electrical wiring? Do you open up and tuck them into the nearest wall or how does it work?
Start by contacting the board and obtaining their permission.
You're lucky to have only one wall socket in the wall. The feed to this socket most likely comes from the ceiling box. A reconnection there and the socket is powerless.
A small construction company or a carpenter can help you take down the wall. A simple job that shouldn't cost more than what is mentioned above.
