This was my first time renting a room (instead of a whole apt) and it was a great experience. I stayed for 7 days and there were no awkward situations, because Astrid has her own private space and we were out working most of the time. I didn't meet her during check in but she made the key pick-up arrangements very smooth. Her apartment was conveniently located: surrounded by lots of local restaurants, bars, market, etc and 10 minutes on foot to the city center. I would recommend this listing to any single traveller going to Vienna. Thanks Astrid!
