The appartment is great and just as described. It has everything you need; e.g. a firm bed, a great couch, a very big shower, a spacious refrigerator, lovely decorations, a big desk, a nice kitchenette etc.
Louise is a lovely host. She answers very quickly and has given us very good recommendations for restaurants, sightseeing, transport, luggage (and I'm sure, she would have given us more recommendations for other things if we had asked).
The location is perfect - many restaurants, bars and shops nearby (also a good supermarket). The MTR and the airport express station are also only a short walk away.
Just book it!
