Werner and Sabrina have a great space. It's super convenient from the train and Werner gives excellent directions.
The space is super clean, within walking distance to a lot of things (we like to walk though) so if you don't the train is about 200m from the front door.
In the neighborhood there are some shops, markets and restaurants, just make sure you have cash for the restaurants.
We had a great time in Vienna thanks to Werner's suggestions.
