Very highly recommend staying at Sigrid's place! By far the best Airbnb experience I have had.
Sigrid greeted me and my partner at the door and showed us to her place. She was very generous with her time and gave us very good tips to exploring Vienna - cool places to eat, drink, the best sites etc.
The room is as described and is represented accurately in the photos. The place is nicely decorated with art and has a nice vibe. Nice quiet place to rest in the evenings after a day of exploring. Or after running the Vienna City half marathon! Nice touches such as chocolates on the bed on arrival.
Sigrid was also extremely accommodating - she made us an amazing breakfast everyday, including a perfect pre-race breakfast.
The location is also fantastic for accessing the the city - very short walk to the train station, and taxi-rank just around the corner.
