Very nice, central location 5 mins away from Wien Hauptbahnhof and only 1 stop to the airport on the Rail Jet, which runs every 30mins. Overall nicely decorated studio with fully equipped kitchen and close to Belvedere. There are 2 issues I would like to mention though - the description says there is no air conditioner (this is clearly stated), however there needs to a working fan provided in the summer because it was 32 - 34 degrees outside. We had to keep all windows open to try and get some cold air, but it was very noisy outside and we could barely get any sleep, which made our stay difficult. There was also an issue with the kitchen sink / ants which I have mentioned in my private comment that needs to be fixed.
