The apartment had plenty of natural light and the bathroom was very good. The location is great too, very close to a station, and an easy walk to the city centre. Mario was a wonderful host – clear in his instructions, and very quick to reply to any questions we had.
We were disappointed, though, that the description in the listing didn't always reflect what was the flat was actually like. It was described as luxurious, but the cooking and washing facilities in the kitchen were tiny. In other words, it was basically impossible to cook a semi-decent meal, which was a disappointment, because we had hotel stays before Vienna and were looking forward to some space and being able to treat the flat as a "home" of sorts. No photos of this particular area of the kitchen were included with the listing. I've pointed out this and other irregularities in the ad to Mario, and I have to say he has been very understanding in his response.
