My friend and I booked Ursula's room for two nights. The appartment is well located; near the Museum's Quarter and a beautifully Church.
The room was clean (no dust) but not exactly like in the pictures and a little messy, with cushions everywhere. Also, as mentioned in many comments before, there wasn't any curtains on the bedroom's windows to hide from the neighbors in the front which wasn't very good for intimacy. However, the bathroom was very clean and just in front of the bedroom so it was convenient.
There was somd issues;We had only one pillow when we actually booked for two person. Since we noticed it at night, it was not possible to ask for a second one. Moreover, the description of the room included wifi, but actually when we asked Ursula, she told us to log into a public wifi from the bank in the neighborhood. It was also pretty chill in the room for winter; one of the heater didn't work and the other one wasn't warm enough, and we couldn't figure out how to use it. We asked about it by text but the host just gave instructions instead of helping irl to fix it. The house is not well isolated some of the wind comes through the window.
We really enjoyed Vienna though! And as museum lovers it was cool to be at walking distance from several museums. And there was many restaurants nearby.
