The apartment is amazing. It is big, very clean and contains everything we needed. The location is also great. We traveled with 2 kids (2,5 and 1 year old) and were able to walk to most of the prominent Viennese places in 10-20 minutes (Stephansdom, Hofburg, Rathaus, Staatsoper, Hundertwasserhaus, Stadtpark, Prater, Augarten). The metro stations Nestroyplatz and Schwedenplatz gave us fast and easy access to the rest of the city. I highly recommend Gudrun's apartment to everyone. Thank you Gudrun and Jean!
