I arrived in the evening. They weren't home, but Chris left a note with all the details. Later on Chris showed me around the house, which was in all in good order and clean (as I keep my own house). I didn't speak to Hong until the last day beacause she was away, and Chris was away a lot. They were both very nice. While I was staying there were other guests staying as well, which was no problem.
The pictures give a good representation of the house and rooms. Braekfast was not provided, but that was no problem for me. There is a small shopping center nearby with a good supermarket and a 5 minute drive will get you to Hornsby, with a big mall and everything you could wish for. Public transport is good during the daytime, trains are 15 minute walk. For good evening connections to the CBD ,park your car near Hornsby and use that station.
I think the place is good value for money and will consider staying there again if I'm ever in Sydney again.
