I stayed here for four months during a sabbatical and I can't say enough about the location of this place. It's walking distance from everything you need for a great stay in Vienna. Three grocery stores inside a block or so. Bars, bakeries, parks, coffee shops, bus, tram, and subway all within minutes. Very fun and hip neighborhoods within walking distance of interesting places like Neubaugasse and late-night music scenes like Thalia. You're at the Innenstadt by bus in 10 minutes and can walk there in 20 minutes or so. Safe neighborhood. Much of my time was in the very early spring so the windows were closed a lot. In that case, it's really quiet and entirely free of traffic noise. I had very few issues but the two or three times I contacted Ronald, he replied right away with a solution.
