Iris's place is really cozy and comfortable. You can also have your own washroom,which is really rare among other airbnbs. It's close to the subway station so you can go to any famous places in Vienna conveniently. Iris and Just are very friendly and would provide all the help you need. Just also took me around the Vienna city and recommend popular local places for me. I do appreciate that. I also had a dinner with their friends and little Nicolas. I would defiantly visit them if I got time back to Vienna. Highly recommend!
