Annemarie and Motti's place was a very nice place to stay.
In general it was quirky and fun little place. Having a washer and dryer was a huge plus for us halfway through a 2-week trip!!
The hosts were pleasant and attentive - more so than expected since our stay coincided with one of the Jewish holidays and we knew they would not be home. They still managed to meet us and show us around and the flat (including the warning about the steep stairs that other reviews mentioned) and even checked in again during our stay, offering to bring over any items we needed.
The location was perfect - just outside of the main area of Vienna. Walking distance to anything needed including transit if you wanted/needed to venture farther out.
