This is an excellent apartment. Very spacious, modern and well equipped, with a nice roof terrace. Door codes rather than keys make life so much easier for check in/out. If anything the information on the Airbnb site doesn't do this place justice. There are 3 large double bedrooms, each with air conditioners, and plenty of living space. Suzana was very quick to respond when I had questions and dropped off extra bedding when we requested this. One useful tip we got from Suzana is if the air con stops cooling (error code E3), turn off the electricity at the fuse box in the closet for 2 mins and this fixes it. Tram 62 to the centre stops right outside and there is a tabac to buy tickets very close by. Overall, this is a great choice if you are visiting Vienna and I would stay here again myself without hesitation. Highly recommended.
