The decor is breathtakingly grand, the high ceiling make it very spacious, feels like a state room :D. The location is not the most central but it is very walkable to the metro station and Vienna metro is surprisingly easy to navigate even though idk a word of German. The WiFi connectivity is so strong I can still connect even across the street.
The floor could have been cleaner but it’s acceptable. The water heater has a mood of its own. Drainage may be old and easily clogged. Walls are thin and you can hear your neighbours quite clearly, even coughing. May be an issue for extremely light sleepers.
