We were surprised given how positive the reviews are. On checking in, Katarina asked us for EUR 2.20 for a tax, it was abnormal given that money transfer shouldn't occur outside the Airbnb platform and that it could've been incorporated into the price.
She then told us that she had been cleaning from the "previous guests from India" and that "she had never seen so much blood". She said it had been everywhere and we were totally grossed out and didn't take our shoes off inside for our stay.
There were 2 selfie sticks on the kitchen counter with a sticky note saying they were for sale for EUR 10 and laundry soap for EUR 4 per load. She told us we could text her next time and stay for EUR 50 cash to avoid the additional fees and taxes.
Katarina was cheerful and friendly and provided great info on Vienna but we were a bit thrown off by the introduction. The apartment is a great location close to metro stations but unless you are interested in a bloody yard sale and some unpredictable behaviour I would look elsewhere.
