Beautiful, modern top-floor apartment with roof access and lots of natural light. Check in was very smooth, and it was nice to have keycards instead of physical keys. The apartment is spacious and well furnished - we especially appreciated the split king mattresses. We didn't cook anything but the kitchen looked well stocked. The wifi worked well and having an air conditioning unit in each bedroom was very nice. Unfortunately we ran into some quality issues with the shower spilling a lot of water onto the bathroom floor, and a loose handle on one of the doors. The apartment is located pretty far north of the Vienna city center, so it'll take around 30-40 minutes to get there by metro/tram. There also aren't as many food options as there are across the Danube river.
