Crystal is very friendly and responsive. Despite being away, she still responded to questions and messages promptly. She did all she could to ensure that our stay was as comfortable and hassle-free as possible.
Her property is conveniently located, not far from the MTR, local eateries and the HK Convention Centre. The apartment is setup more as a hostel than a homestay. 2 rooms are ensuites whilst the rest are not and they are all very comfortable. Very clean and looks newly renovated in stark contrast to the apartment's lobby and the building. The photos in her Airbnb page will give you a accurate description of the apartment.
I would stay at Crystal's apartment again and recommend her apartment to anyone thinking of visiting HK.
