We are absolutely satisfied with Votiv-apartments for our three-night stay in Vienna. Close location to city center and university campus, 3 min to subway station, still in quiet area. We slept with open window, however street noise was minimal. Particularly convenient was that apartments are just behind Votiv-church, which makes it easy for orientation. We arrived to Vienna early morning, and it was nice from host to allow us to check-in in the morning.
Space in apartments is small, but sufficient for two persons. Everything in apartments is of high quality. Being in Vienna we would definitely choose Votiv-apartments for our stay again.
