I loved this flat. It is beautifully decorated. The location is fantastic, either a 30 minute or so walk into the centre or a very quick journey on the tram (the stop is just at the end of the road) or metro (two stops are a 5 minute (approx.) walk from the flat). There is a lift to the flat, which is great with your luggage. Osnat is very quick to respond and check-in and -out was super easy. This flat comes highly recommended for your stay in Vienna.
