We stayed 2 weeks in the appartement.
The light did not turn off in the first days, first night we could not sleep because of the light coming through the door.
The boiler made noises every 5-10 min, pretty loud for the whole stay. As a webinar speaker I was not able to record anything there because of the noises. It was a business trip. So I needed quite surrounding.
The technicians came to fix boiler & lighting in the first day of our stay, but did not change the situation. Boiler still made noises and lighting still did not work properly. In the beginning the light did not turn off, then the same light did not turn on after the technician came.
WiFi connection was not stable & sometimes weak.
Washing machine had smelly water in it. I did not wash my clothes there.
For cooking: there is no pan, just keep that in mind. There are pots, so you can boil something. Everything is closed in Vienna, so you have to cook or use food delivery.
The stay was OK. But it would be a lot better if everything worked well. :)
Its a very pretty appartement. Stylish & luxurious. Great design.
