I don't believe the listing is accurate as the apartment is really a 1 bedroom with a living area that doubles as a bedroom. All the amenities are in the living area and it is not suitable to rent as a "2-bedroom." This generally seems to be a trend on Airbnb nowadays where the photos look pretty good but the lack of layout information causes problems after arrival.
Our party of 2 needed two bedrooms but the reservation required booking 3 people to allow use of the second bedroom and the price was almost double. This is a request for guests to materially misrepresent the nature of the stay. (However, the 1-bed aka "studio" arrangement is pretty good value for Vienna).
Otherwise, the host is responsive and generally helpful. The space is modern and the interior is well-lit. The location is a bit on the outskirts and the neighborhood isn't particularly lively although it is very close to supermarket/grocery. The elevator was good for moving bags.
