Overall, the listing was nice and our trip to Vienna was very pleasurable. The apartment was clean, had some nice art, was plenty spacious for two people and public transportation (just like everywhere in Vienna) is very easy to use. Communication with the host was quick, though very incorrect on one account. The kitchen could use some more equipment (i.e. it did not have a large knife, a cutting board or a water cooker), but it was manageable for breakfast.
A large issue to us however was the internet connection and the incorrect communication regarding it. Just after booking this listing I got a digital job interview with proposed time slot during our stay, so I asked the host whether the internet would be able to support that, or if I should set a new date. She "was positive" that it would be fine, so I accepted. Upon arrival, the "welcome to our apartment"-letter had an instruction for what to do in when issues arise (reset the router), so those issues occur frequently enough that all guests have to be informed directly upon arrival. And as you might have guessed it, internet indeed was not stable at all and very, very slow. I ran a speed test, which told me the speed was 1.24 mbps -> not even enough to run Youtube in 360p without regular buffering!
Normally not having good internet on holiday is not that big of an issue to me, but lying about it before our arrival definitely is.
Though you should be wary with what the host claims, if you do not require a stable internet connection for meetings we would still recommend this listing.
