We stayed here for 4 nights and can say that this hotel is really 5 stars. We stayed in the Krungthep wing and it is next door to the BTS, very convenient. The butler was fantastic and really looked after us and ensured I have some cold beer in the fridges after a long day out in the heat. The hotel decoration was very decadent and the pool was fantastic.
Breakfast was huge with an amazing array of offerings. Overall I would HIGHLY recommend staying here.
