What a great experience staying with Hong and Chris! They are such an inviting, warm, open, friendly, generous couple. Felt like part of the family during the three week stay! Their home is open to guests; you can cook, relax, enjoy a chat, watch TV or sit on the deck outdoors. The neighborhood is lovely, transportation convenient with a bus stop one minute from the house. Groceries along with some eateries and a coffee shop are available nearby, and if you don't mind traveling a little (by bus or train), one can go to Hornsby. At the Hornsby train station (a bus stop is also there) you'll be dropped in a bustling city with a nearby library, all sorts of shops, outdoor vendors selling fresh produce, take-away foods and more; there are outdoor cafe's, nice selection of dine-in restaurants and a big beautiful shopping mall.
Though Sydney center is a little distance away, the train system makes it easily accessable. I made the trips many times to see various attractions (including Vivid Sydney, which was quite a display).
Thanks for a wonderful stay!
