The apartment is really large and comfortable. Also well located, just a short walk from a well connected metro station. The place has a good wifi connection and Michael left for us a map from Wien which helped us a lot.
Although we haven’t met him in person, he was fast in answering our questions. We are from Brazil and not familiar with European winter, so we found the apartment little cold during the first night (20 degrees Celsius inside). Michael told us how to reconfigure the heaters to a warmer temperature.
It was a very pleasant stay. We had great time in Wien.
