After doing some research, we've decided that R will come to Dublin on 14th and we both will fly to Stockholm on 19th. Between us we have 60 kilos of weight allowance and I'm prepared to pay for some extra kilos as well. We'll send books and some heavier stuff via post and one of my colleagues has agreed to take a few things with her when she moves back.

Renting a car was just not feasible, neither was using a moving company or a courier. I don't have that much stuff, but they wanted about 2000 euros to transport it to Sweden. Not gonna happen.
