2 female students are looking for accomodation in vienna Jan7-March16

Hello everyone! We are two female Master students (22 and 26 y.o) , coming to pursue our internship in Vienna from January 7 untill March 16. We need a place to stay for the internship period. We are looking for studio, or one room apartment, or a room in a shared apartment which can fit 2 people ( 2 sleeping places or double bed is fine :) ).  We would prefer the apartment to be as close to the OSCE secretariat ( we will do our internships there) , as possible ( up to 20 minutes walk would be perfect). apartment in 2nd district would be great as well. We are clean, positive and quite.  Elena Samar
