We have stayed at the Banyan Tree Bangkok twice now and both times were excellent. 5 star hotels in Australia are pathetic compared to the 5 star service offered in Thailand - the Banyan Tree corridor walls are literally lined with silk. Each day there is a new essential oil burning in the common areas, the rooms have a wonderful view of the city and the beds are very comfortable. I also love the big deep baths that come with complimentary bath oil, salts and bubbles - so nice after a big day of sightseeing.
We got a welcome bottle of wine on arrival and fresh fruit plus a newspaper daily. The buffet breakfast included in the room price is also of a high standard. It's so indulgent to sit outside under their beautiful tree, sipping champagne and reading the paper in the morning.
