This was the cleanest apartment I have ever seen!!! Communication was a breeze. It was easy to check in. They left us a bunch of booze and panettone as well. Parking in this area is usually a nightmare but after you do, you won't need your car for the rest of your stay. I don't think you could get more central than this unless you slept in St. Stephen's Cathedral. The beds were super comfortable, the kitchen was well equipped. Our only problem was (this is a problem in all old buildings in Vienna) the water pressure. Water pressure is ok at best but when both showers were going, it was all up to gravity to get the water out of the shower head. We showered separately after that and it was fine. There weren't guests coming right after us so we checked out at 3 I think. Either way it was awesome. Highly recommended.
