The point that I have no WLAN in the advertisement of my flat is that I had bad expirience with one guest of the theater who spent all my 6 GB within one night loading down films - and then I had no internet for the rest of the month
This is why you will not find WLAN in the description of my flat. Because then I would have to take unlimited internet with a much higher price - and even it is unlimited the speed will go down when spending a lot of gigabites.
I am happy that you nevertheless had a great time in Klagenfurt and hope to see you again somewhere on this world!
greeting from sunny Klagenfurt
