I have stayed at a number of five star hotels in Bangkok and around the world and this one definitely meets the criteria from the professionalism, attentiveness and friendliness of the staff to the quality of the food through to the luxury of the rooms.
After a long haul flight just 24 hours here had me feeling like a new person. The Executive rooms and suite complete with living\dining room is spacious well equipped and comfortable. Good quality linen makes for a wonderful sleep after a lovely soak in the stand alone bath tub and being refreshed in the rain shower before sitting down to a sumptuous breakfast certainly had me feeling like a new person. Being able to relax in the executive lounge is great if after a day in the city means you want some downtime and quality relaxation. Dining experiences are equally highly recommended even if you're not staying in the hotel.
I definitely will be making this my choice when next in Bangkok. Top marks for everything.
