We loved the sunny, modern apartment at a very convenient location, a <10 min walk away from the central station and not too far from the city centre (30 min walk). Everything was clean, the pictures were accurate and the view was spectacular.
Despite being so close to the central station, the windows isolate really well, so no need to worry about losing your sleep over trains braking frequently right underneath.
Will definitely consider this place again when we're back to Vienna!
