This is a great steal for Vienna! The apartment is perfectly located less than a 10 minute walk from Wien Mitte Station and less than a 30 minute walk from the Hofburg, Albertina, Belvedere, etc. It is also in a pleasant area where people are walking dogs all the time. :)
The apartment itself is extremely clean, and it is very accessible. The person who checked me only spoke German, and even though I don't know any German myself, I was able to understand everything she told me pretty well.
I did find the apartment to be quite chilly, though, but perhaps this was because the weather was just a tad too warm for the heat to come on.
