We stayed for a few night and wish it could have been double that. We loved everything about the apartment, it was very clean, bright and large, and loved the high ceilings. Directions to the flat were very good and Stephanie allowed us to drop our bags early as the storage key wasn't available which helped a lot. We didn't manage to meet Stephanie but that wasn't an issue at all, she was on call when we her. I'd definitely be happy to stay again, it's in such a convenient area and is the perfect apartment as a base to see Vienna.
