The cost-benefit was good. The apartment was smaller than we expected (especially the bathroom) but for two people totally fine. It was mostly clean but a little dusty (talking as an allergic person) since we found ourselves sneezing a lot in bed (where the bed sheets also had some stains on it unfortunately). The apartment is well equipped, even though a little worn out due to the many accommodations as stated in another review. For tourists a good place when you won't be staying inside a lot anyways. The check-in was very easy, the location is well-connected and Birgit was very friendly and helpful. Overall we had a nice stay in Vienna!
