21 years old boy looking for a flat-share in Stockholm

Hi everyone!
I am a 21 years old French Geo-sciences student that have been recently accepted to study at Stockholm University for the ongoing two years (Master level). I'm therefore looking either for a flat or a flatshare in Stockholm to inhabit it from ~approximately the beginning of August (max rent 9000 SEK/month).

I do not smoke, nor have a pet, but I am normally not disturbed by persons that smoke, reasonably, around me, or have a gentle animal (would prefer an independent cute -clean- cat than a dog if an animal was to happen in a flat-share, though..). Above all, I would prefer to share a flat with some Swedish buddy as I am very interested about Swedish culture (and in the correlative learning of the language). I am as well interested on meeting some buddy that would be seeking to search a flatshare in a group-fashion.

Cheers, Xavier
