The place is really nice. If you want to stay in a comfortable place but cheaper than a city center - it's perfect. However if you come by car - it's quite problematic to understand the rules of parking, be aware. You can park car nearby on a P+R parking, for just 3,4E per day, but on the street you have to but parking tickets in the nearest tabaco (open only utill 6PM). Comong back to the flat itself - it's really clean and well firnished/equiped. We had a bad luck(I hope that's how it was), the elevator wasn't working and the entryphone too, so we had some additional training up and down (the flat is on 2nd floor EU or 3rd US). If you want to split with friends ask for the extra keys before, otherwise you may have a problem. We haven't meet Ellena(host) in person, but she was doing her best to help us. As general - great place to stay while in Vienna,
