Unfortunately, I am having to give this stay a negative review. The flat itself is nice enough, but the host a disaster. On arrival at this Airbnb, I was greeted by the host and an aggressive male relative demanding €300 cash saying she "got the discount fee wrong”. Prior to my arrival she had accepted me as a guest on her advertised fee and taken initial payment. After an unpleasant argument, they finally accepted I would not pay any additional fee. On departing the place a week ago, she claimed I have caused her financial damages by not sending her my Deregistration Form (an Austrian register with the council, which holds much of my personal information on it), which I am not legally required to send her (although you are legally required to deregister from an address within 3 days of moving - note to anyone moving to Vienna). Even though I told her I deregistered from her address, she insists she is entitled to a copy and will charge me a daily fee of €41 until I do so. I have formally raised this with the Airbnb complaints department who confirm this is unacceptable. Vienna itself is a beautiful city and I highly recommend visiting - just choose your accommodation wisely.
