[Metalab] Apartment/room wanted December 6th to 19th

Hi all, (my first opportunity didn't work out after all, so I'm trying again) I'll be in Vienna December 6th to 19th! ..and I'm looking for an apartment or room which I could rent for any subset of that period. Does anyone have or know about anything decent? (Preferably in walking distance from the Metalab) Cheers, -Marius
