this was really terrible. I have been using Airbnb for many years but this place is the apex of what greed can produce. the rooms are tiny, 10m2 including bathroom and kitchen. I am sure that this is illegal in Austria. you get one tiny threadbare towel, and the bedclothes are lumpy and cheap. the single mattress already leans to one side. there is no sound insulation, so you hear everything from the at least three other "apartments" packed into a normal small apartment size. there is a system of codes that allowed me to get in the first night but didn't work the second night. I messaged the owner to no response and only received a reply much later after contacting Airbnb. then I was told that the key was under the mat!. I subsequently had a sleepless night through the Noisy arrival of other guests trying to get in and pounding on the door, from 11pm to 3am. I could hear the sounds of their voices,the bathroom ventilation and the showers as if they were in the room with me. when I got up at 5am to leave, I found that the main door had been forced open and had been open all night. please investigate this place.
