Great location and easy to walk to many sites. Communication with Eva was good and check-in was simple. Apartment is very quiet, no noise from neighbors and double-pane windows keep outside noise to a minimum at night. Bed was comfortable, softer and more absorbent than some hard/firm beds in some AirBnBs. Lighting is minimal and a bit of a problem in the bathroom when putting in contact lens. Bedroom has shades in addition to curtains to block morning sun, so look for them - though a lot of light will stream in from kitchen window.
Overall, a very good place to stay in Vienna at a reasonable price.
