Sweden is a good country in many aspects. Each and every country has its own peculiarities and Sweden is not an exception. After almost 2 years of living in Sweden, the worst thing that I have faced here is bureaucracy. There could easily 2 institutions sending you back and forth saying they need a paper from the second one before the first one can proceed. If you need to do something about documents, registrations, dealing with the mobile, cable and internet providers and any kind of paperwork first you will be in a line for half an hour, then there will be a different person than the one you talked to yesterday and you will have to tell the whole story again. And the answers from different clerks of the same institution could be insanely different. Most of the time they just do not care and are really happy to send you to another person or tell that someone is on vacation and you should come in 2 weeks. There are exceptions but you need to be lucky to get lucky. Even Lithuania was a bit better in this case.
