Okay but not value for money
It may well be that the rates offered through travel agents are a lot more attractive, but I booked through Asiarooms and got what I expect is the standard online discount.
For the same price as a 5-star luxury in Bangkok such as the Sukhothai, the Settha is vastly overpriced.
The staff are very nice, so is the building and the rooms are just fine. But it all feels a bit incomplete and vaguely amateurish, and lacking in atmosphere, like a provincial outpost. For USD 150 at the max, this would be ok value. Not at USD 225.
