I loved this apartment! It was so big and so cute! The bed and the couch were super comfortable, and the towels were soft. She was really helpful with check-in as I went to the wrong building at first (totally my fault!), and she helpfully guided me to the right building over the phone. I didn't notice any outside noise, and so I slept like a baby! The apartment was maybe 5-10 minutes by foot to the subway, making it convenient to get into and out of the downtown touristy areas. I would absolutely stay here again if I got the chance to visit Vienna again!
