Stayed during our visit to Vienna to see all of the wonderful Christmas markets. Albert's communication was excellent, and his father met us for check-in and gave us lots of helpful tips for getting around Vienna. Very good location (only 4 underground stops from centre of Vienna and only a few stops away by tram to the main train station). Very clean apartment, it is a small space so I would recommend to solo traveller or a couple but it serves its purpose well.
