Alexander and Bettina's apartment was lovely and warm. The hosts made us feel so welcome. Check-in, check-out was super easy. The apartment was full of amenities for a family. Its location was perfect, 12 mins' walk to the Opera or 2 stops away by tram D, of which the stop was a few steps away from the apartment. Wien Hauptbahnhof train station was 5 mins away by cab at €7 for a family of 4. Spar supermarket was nearby on the right of the apartment.
