Just to add a few bits:

Stayed pre-christmas for a long block of 12 nights. Was in a basic room which was absolutely fine, larger than I expected, no sofa but a decent double bed and a desk for doing some work. Critically the room came with a kettle, vital for a tea drinking Brit on long travels. The lighting controls in the room seem to have been designed by Mensa to challenge the jet-lagged traveller and it took ages to work out how to turn the lights off. The same switch that turns one light on turns all the lights off if pressed for one duration but turns a different light on. Seriously, why oh why do hotels do this. In addition there was a lack of power sockets within reach of the bed, (as in none) not great for charging phones overnight and using them as a clock / alarm. I'll take an extension cable next time.

Decent gym, lacks a space for stretching but lot of cardio-machines. The pool is shut over the winter months. There is an indoor pool in the sports centre about a 5 minute walk away.

Breakfast should have been fine, lots of choice but was just not well executed. Specifically the coffee (when it hadn't run out) was terrible and the tea cups too small. The cook to order poached eggs were basically raw (and I like runny). I ended up going to Starbucks in the mall (about a 5 minute indoor walk) for coffee and bringing it into breakfast.

Location: Is fantastic. Very brief walk into the MTR station for fast and super cheap trains to the city and a bus station for local services, takes a couple of goes to work out the most efficient path to and from the hotel but it's really easy. Can go running outdoor along the coast to Sunny Bay, or up the trail to the top of the cable car (equivalent of 205 floors of stair climbing). Lots of shops in the mall that's attached to the hotel but bit high end for me. Plenty of dinner choices within the Tung Chung area either in the mall, a 5 minute walk outside to the Curry Lounge (excellent Dosas) , outdoor beer/dinner at Kimos. other options include a Korean BBQ place in Fu Tung Plaza and a bit further away at Yat Tung Shopping Centre some more local choices. And don't forget you can be in the central city in under 45 minutes including the walk to the train with all the food choices there.
