Brand new apartment and everything is really nice and is exactly as seen. No keys just a touchpad which I found so convenient, local to great public transport. It takes around 20 minutes to get to the main part of Vienna, the local area is quiet. The apartment is super clean too.
I had a couple of issues and Manuela was very helpful. The annoying thing was I only had a hand towel to use which isn't great and they were brand new so I was covered in fluff after a shower.
Be aware that you will only get replies during business hours Monday to Friday so you will not get any response on a weekend or after 6 pm on a weekday, which for Airbnb is crazy and not ideal if you had problems like I did with the Aircon not working you are on your own!!!
If you could get replies during reasonable hours of the day I would say this is a 5* property as! I would definitely stay again!
