Excellent as always. Although some rooms are a little dated and there is no indication of whether a room has a shower or a bathtub, the overall experience is still top notch. I would argue that Novotel Citygate is the best airport hotel in Hong Kong due to the fact that it has frequent coaches to and from the airport and its close proximity to Tung Chung Station. There are a lot of things to do in the area and the buffet was superb. If memory serves right, they also have special coaches to SAT exam centers for exam takers. 10/10 would recommend.
Do remember to take a plug converter if your electronic devices use non-UK plugs, though you could borrow one from the concierge, but they only have so many.
