This is the perfect hotel but there is no perfect room. The best room is probably 8817 on the eighth floor. The window in this room has a view of the approach to runways 06 and 07 as well as the holding point for Runway 07. Next to the room is a public area with a view to a gap in the buildings (next to the Loong Air HQ) that allows you to see aircraft taxing to the holding point of Runway 06. So if 06 and 07 are in use nothing will be missed if you are closely monitoring the tracking sites.
If however they are using runways 25 and 24 arrivals turn off before coming into view so will not be seen from this room until they depart. Alternative rooms with this same view are 8816-8802 but each room gets progressively further away from the public window, so it's further to walk.
An alternative view can be had from any room between 8823 to 8837 with the lower numbers being the best due to their proximity to the aforementioned window. The views from these rooms are over the terminal and the approach to runway 25 and runway 24 are visible. Departures from runway 25 can also be seen. Departures from runway 24 are visible as long as they lift off quickly and are not too heavy! However the full climb out is visible from the public window.
The rooms a very cheap and bookable via Trip.com, therefore I would suggest if there is more than one of you travelling together you should get separate rooms. Then ask for one on the front and one on the back to ensure you have both views available. That's what we ended up doing. If there is just one person - then ask for the room depending on the runway direction and choose the direction looking towards whichever approach is in use.
The hotel is on the 7th and 8th floor of a service building, so I think all rooms will have some sort of view regardless of what you book.
There is no restaurant but there is a 7-11 convenience store next door where snacks can be bought. To get to/from the terminal I would recommend getting a Didi (China's answer to Uber). There is a public transport options, however a Didi cost less than £2 and was very convenient.
