We stayed here 5 nights in June, 2019. Sissi’s place is in a great location - a 5 minute walk to important public transit and 3 well-provisioned supermarkets, a 20 minute walk to the inner ring, and a 30 minute walk to the absolute center of the city. The kitchen is well-equipped with all you need for simple cooking, the linens and towels are of a thoughtful quality and the unit is freshly renovated. You should be advised that this apartment (like many in Vienna) has no air conditioning. During our stay it often topped 90° F (32° C). No fan was provided in the apartment. We slept with the windows open to get some fresh, cool air, but traffic makes it very loud starting around 5 AM.
