A nice small apartment very close to the city center. I was staying alone and felt very comfortable. There is a tram station within 2 minutes' walk, another 10 minutes by public transport and you are at the Opera. There is a big Spar supermarket up the street, you can get almost anything there. The apartment itself is very clean, which I liked very much. For my 3 days' stay that was the right choice. The host responds quickly an provides detailed information. So, I would recommend this option to a friend for a short visit to Vienna.
