Christophe was a great host allowing us early access to the apartment and supplying a spare fan. He checked up on us during our stay and was always easily contactable.
The apartment itself has all the mod cons you would need and comfortably fits two. It's also closely located to the train, grocery shops Aldi and Coles and other specialty shops.
Only thing to be mindful of, and it is mentioned in Christophe's description, is that it is situated on a major arterial road and the ambient noise is quite loud even with the windows closed.
If you don't mind the noise then you'll find Christophe apartment has all you need for your stay in Sydney.
