29 y/o German looking for accomodation (shared flat with roomies) in Split for summer term

Hello everybody, my name is Axel, I'm 29 y/o and I will take some courses at the Faculty of Economics this summer (although I'm currently doing my Master of Engineering). I'm looking for accomodation for the time from end of February/beginning of March untill July. Ideally in a flat with some nice roomies. I travelled a lot and lived and for some years in Latin America also with roomies and I got along great with everybody.  I speak German, English and Spanish fluently and can manage some basic phrases in French and Portuguese, so there should be no problems with communication. In my freetime I like to do sport or go for a drive with my motorcycle but once in Split I hope to pass quite some time at the beach
