Overall the apartment and the location is great, you can walk to almost all tourist attractions and Vienna is a beautiful city to walk in. There were slight hygiene problems in the apartment as we thought the bed sheets and the beds were not very clean and there was some hair around the bed and on the sheets. There were slippers for each guest inside the apartment but they were clearly have been used before as they were not packaged and were slightly damaged. Nevertheless, despite minor hygiene issues the apartment is great, check-in is flawless, Hermann is a great host and responds immediately to any questions you might have and the location is great. Don't hesitate to stay :).
