The place is small but good enough for a short stay in Vienna. We had almost everything we needed for a period of 6 days. What I didn't like was that we had the same towels for all that time. Also, it's a small place, but one window is not really enough for either getting enough daylight or air. We had a huge TV, a lot bigger than the one in the pictures, but that wasn't really needed, because it's harder to pass next to it. However, these are just small remarks that someone might find useful, because overall we are quite satisfied. It is worth the price in any case.
P.S. Just one thing that I would change in the description is that it takes you 11 minutes (by Google maps) to get to the subway station from where you take the U3 line to get to the center (Stephansplatz). That means it takes you a bit more to get there, but it's still very close.
