We highly recommend this place to stay while in Vienna! We stayed with three grandparents and three small children. Ludwig provided a quick but thorough orientation to the apartment and everything was so perfectly thought of in the apartment that we never needed to contact him again. We spent a couple late afternoons sitting in the beautiful apartment and listened to music float in through the windows. We had a large stroller and it was easy to get in and out of the apartment with the modern and spacious elevator. We easily walked to most of the major sites from the apartment.
