Can’t recommend Sissi’s apartment enough. It was within walking distance of Friedensbrücke UBahn stop and a short trip into central Vienna. Sissi very kindly allowed us to leave our luggage before check in as we arrived very early in Vienna. This was fantastic as it meant we could go off and enjoy the day without worrying about our bags. The TV in the flat had Netflix (use your own account) which was fab and we had built in entertainment in the evening. Sissi is a fantastic host, really helpful, the flat is fab, I would stay there again!
