Just did a quick one night stay here, arrived 8pm on a Saturday and left again at 8am the next morning. As Plat was 'upgraded ' to an executive floor room which I guess is the same as a regular room, but on the same floor as the lounge , so I guess it was nice to walk there without taking an elevator. Rooms are fine plenty of space but nothing special. Welcome amenity at check in was $10 f&b credit or 1000 points, breakfast in lounge with no restaurant option. The bar in the lobby seemed to be quite lively but did not partake. Lounge open until 22:00 with snacks and drinks. There was red/white wine and San Miguel beers, and alcohol appears to be available all day not just at happy hours. There were only about 10 people in there at 8:30pm on a Saturday.
Breakfast in the lounge was good, small selection but all you need, egg station, even sparkling wine. Lounge staff super friendly and helpful. Lounge doesn't open until 7:30 which might be an issue if you have an early flight.
Shuttle to/from the hotel was right on time and took about 20 min from T4 to the hotel as it has to go to all the other terminals on the way back to the hotel. From hotel to airport we lined up at 8:10am for the 8:30 shuttle and there were some people who arrived 10 mins after us and didn't get on so suggest to be there early. Below is the current timetable.


All in all I would say this property is fine for a quick stopover but would not be expecting too much more than the basics, aside from a good lounge.
