The location is ideal for a trip to Vienna - a lovely neighborhood which is just far enough away from the touristy parts to avoid the crowds but an easy walk to anywhere you’d want to go. And well served by public transportation.
They are perfect hosts - very communicative and extremely helpful with everything (from how to get there to excellent recommendations for local restaurants, cafes etc).
Plus the apartment comes with this amazing portable WiFi which you can take with you all over the city and is a very helpful bonus.
Would definitely recommend!
