I moved from Sthlm to Zürich after a few years in the Swedish capital. I looked at different options, and in the end, I discovered/concluded that the easiest option by far was to use the simple snail mail office. I mailed myself from Sthlm to Zürich a total of 10 banana boxes, carrying clothing, books, kitchen appliances etc - the usual stuff you would imagine that is collected during a few years somewhere. Each box cost me approximately 700 SEK, which multiplied by 10 made around 7000 SEK - this was still cheaper than any transport companies I talked to at the time.
I had some furniture as well, but that one I decided to drive myself by car a few months later.
