Stayed here with Family of 6 (3 kids), apartment was bigger than we anticipated and very comfortable/clean. Washer/dryer was a plus as we were taking a road trip with light luggage, so we were able to wash everything there. We got there late at night and Harry left keys for us in a dropbox, no issues. Area is 5min walking distance to transportation hub, but it is close enough to centre Vienna that we ended up walking everywhere. If arriving by car, parking is limited on the street to 1-2 hours max during the day (9am-10pm) but there is a parking garage 5min walk that we used. There is an elevator in the bldg but you can miss it since it is facing an inner courtyard on the ground floor. Communication with Harry was very good, and while we didnt have a chance to meet him because we arrived late, he would answer all our questions right away via email.
