My stay in HK at Gordon & Melissa's place was a unique experience. Gordon took a lot of his time and guided me through his neighbourhood while providing me so much information.
Also their hospitality was absolutely amazing.
Just a story: Due to supertaifun "Mangkut" my flight from HK was cancelled and rebooked two days later. There didn't arise a single problem with spending two more nights at Gordon's place, although a new guest arrived the day before my departure. Gordon cared a lot about convenience and safety.
I can't imagine a better place for single travellers to explore Hongkong and definitely would recommend his place.
