I just can recommend Audrey and this nice studio in the Westbahnstrasse. You´re close to everything in Vienna (really! - museums, shops, supermarkets, restaurants, public transport, etc.) and in the studio you'll find anything you need. If you have questions, just ask Audrey. You'll get a rapid and detailed answer to all of your questions. Is there anything negative about the place? Not really, just depends on how "church bell resistant" you are ;-) I didn't care and really had a great time there.
