Afternoon Tea Set: Enjoy Mariage Freres' afternoon tea with snacks from 2:00 PM to 6:00 PM amidst nature and the grandeur of the luxurious hotel lobby, with tall pillars reaching to the ceiling and the beauty of the art of exquisitely painted murals on the walls, complete with a variety of flowers, and staff who provide excellent service and care.

Stayed for 5 nights, the pillows were very comfortable. While the rooms are old, it is luxurious though the standing shower can do with some maintenance to bring it to 5 stars. There were mosquitos inside the room and the team were quick to bring in electric repellent.

My third time here based on my very pleasant stay the last two times, but the bubble bursted last evening when a gourmet festival held in the hotel turned into a late night disco party. The hotel is a hollow retangle with all the room doors facing the atrium where breakfast and evening bar take place. Any sound from the atrium area travels upwards and trapped in this retangular hollow design. We were back in our room on the 5th floor at around 2200 hr last evening with the music already blasting and blarring which we thought would subside soon ..... well, it lasted till 0015 hr and after 2 complaint phone calls to the reception. The receptionist,to be honest tried to be helpful over a matter that he had no control over. We chose Anatara cause it used to be a quiet and peaceful haven in the bustling city ..... so we accepted the tired decoration (we just found termites all around the coffee machine in our room), the ongoing renovation and the closing of the swimming pool during our stay .... but last night was the definitive sign that it is time for travellers to move on. Bangkok is not short of accommodation choices of all ranges.
