We had a great stay at Mara's place. The apartment is large, bright and spacious - just as described! And very clean. Unfortunately, we didn't get a chance to meet the host in person, but she was very responsive over chat and helped us all the way through. There was also a very thoughtful printout left in the apartment which had suggestions of what to do, places to eat, etc. The apartment is in a great location, close to public transportation and is perfect if you prefer walking around town as well. Highly recommended if you're looking for a place in Vienna.
