Great location, U-bahn is 100m away, supermarket near as well. Also, from Harald’s place one can walk all the way down to Schonbrunn palace through the park - quite cool experience. We had minor electricity issues (plugs) but not a big deal at all. Harald was very responsive to all the queries we had, checkin pretty smooth too. All in all, amazing experience and I would recommend Harald’s place to everyone interested in exploring Vienna.
