We had a great stay at Vienna's flat.
Very clean and simply decorated, the location and the little outdoor terrace are a big plus. There is a beautiful selection of toiletry products, way beyond what you would come to expect.
If you don't know much about Hong Kong, Sheung Wan and especially Hollywood Road (just next to the flat) are a great way to get you started while being very accessible and full of great coffee shops and restaurants. It's also a short walk away from Central/Soho.
Vienna has been very welcoming and flexible, which has made our stay only better.
Highly recommended!
