My husband and I stayed at Caroline's place for a few weeks and very much enjoyed it!
The value is great for Sydney and it is in a great location that is walking distance to some of the best spots in town! Caroline is also a responsive host and is happy to help when you need it, when we had a problem with the internet she resolved it within minutes.
My husband is very picky about noise and Caroline's place was perfectly quiet at night! We could not hear the neighbors at all. The apartment is facing a quiet street too, so the hustle and bustle of the city was avoided.
We would definitely recommend a stay here if you get the chance! It's a great find in Sydney!
