We had a very pleasant stay at Dan's place. Be aware that the whole house is full of Airbnbs and it's not managed on site, check in and out is without any personal contact to the host. But that didn't bother us. We liked the flexibility and it was pretty quiet inside the house.
The streets can sometimes be a little louder at night due to the Traveler Shack around the corner, a student club which is open every night till late. If you're into that, it's fun to go there for some cheap drinks.
The location is great. Shops and restaurants nearby, as well as tram and subway. You'll be very quickly at places like Neubauviertel, Schloss Schönbrunn and the city center.
The apartment is very spacious with three comfy single beds and a sofabed. Kitchen has basic things for cooking but only one cooling plate, which is with induction tho, therefore very quick. For simple meals it's enough. No oven or dish washing machine in the apartment, but a washing machine and clothes hanger. Overall it's alright for the price.
Communication with Dan was good, thank you a lot!
