Overall the hotel is good, room is comfortable and sound proof is good (especially near airport) and not much door closing banging noise. Room is clean and breakfast have good enough choices of food and drinks.
Environmental friendly hotel with shampoo, washing gel etc are in big bottle. But there is no toothbrush and shaving kit etc unless you request (and probably go to reception to get it is faster).
Very expensive if you are in peak season (for my case is exhibition period, so it is 3 times more expensive than normal).
However, there is one point need to note is the location of the hotel. It is so close that even taxi driver do not want to take me there, he told me to use skyrail. So I google it and found it is 15mins work from there (maybe in day time have bus can go there, but I arrived at 10:30, maybe no bus running (anyway, that is google map suggest and I just follow), the road is not nice when it is dark (I need to use phone torch to light up in some part of the route). Maybe some other hotel near train station will be better if I choose to take public transportation or do not want to walk that much (and in the dark).
