This place has an amazing location, so easy to and from the airport on the S-bahn, and into town. Prater is 5 minutes walking distance. The room is very good (old Viennese houses style). Private toilet and bathroom (but accessed across the entry hall and kitchen common to the hosts).
Theresa and her parents were super helpful and friendly, and assisted me with a early check-in. Would happily back again in Vienna and stay with them.
Thanks..!
