I booked this place for my parents who were visiting from the US. Ingebord is extremely easy to deal with - she's friendly, communicates proactively and allowed us to check-in early. The place is in a lovely pre-war building that has been very well maintained. It's on the 3rd floor, but there is a mezzanine, so it's actually on the 4th floor of the building (or 5th, by American standards), so it's very helpful that there's an elevator. The location is extremely convenient, with a U6 stop and tram stops just a couple blocks away. It's on a somewhat busy street, with two trams lines and two lanes of traffic. The bedroom is on the street facing side of the building, so you will hear some noise at night. But Vienna is not a noisy city by most of standards, so the noise is really not bad and it didn't bother my parents who live in a suburban neighborhood. The interior was spotlessly clean, comfortable, and immediately feels like a home instead of an apartment setup for Airbnb use.
