Irmke was an excellent host. Although she was out of Sydney when we arrived, she has arranged everything beforehand, so that everything was ready for our stay.
We stayed at Irmke's place for two weeks in June and enjoyed her spacious, very clean and neat apartment with a bay view. If you want to explore Sydney, this location is definitely a good choice. The place is close to city center and is about 5 minutes walk to the train station.
