Estrella's and Gerald's apartment matched the description, the location was perfect for us for where we needed to be in Vienna plus it's only a short walk to the CAT station, so if you're coming from the airport it's very convenient and on the way back you can check in your luggage there already in the morning.
The outstanding thing about this apartment were the duvets - the most fluffy and cosy I have ever seen at any rental place or hotel! A very welcome feature in December!
The directions and explantations provided by Estrella were so clear, we had no need to communicate during the stay.
