Vonette place is in terrific location, a short walk to endless public transport options. There is something happening on almost every street corner and the famous night markets are less than a 3 minute walk. The building is private, quiet and secure. For those of you who like a tipple, turn left out of the building and cross the road and keep walking about 2 minutes. There's a liquor store there with boxes stacked on top of each other, it's looks a real mess but you can buy beer, wine, spirits and mixers at low cost. Vonette responded quickly when we messaged her but we really didn't need her, the place and her instructions were easy to find and follow and the apartment has everything you could possibly need, all at a fraction of a hotel room.
My advice would be to book here for part of your stay and book the rest in another place in Central. It will help you experience both sides of what Hong Kong has to offer.
I would also encourage you to do the following:
Race meeting at Happy Valley and Sha Tin. Booking in the Adrenalin Lounge and the Haymarket room is a great way to experience the races.
Foodies Food Tour, this was excellent
If you like live music and dive bars, try The Wanch, you are literally 1 meter from the band and the bar at the same time. This was great fun!
