I have stayed at this hotel years before as well as the other Shangri-La in another country. This Shangri-La, apart from the wonderful river view, well complies with "Shangri-La standards" that are much higher than other hotels of the same level. One outstanding thing which I found with their services was when we used hotel airport return transfer services. Upon arrival at Suvarnabhumi Airport, we were welcomed by hotel staff who escorted us to the check-in counter. She was very nice and attended us up to the escalator to the security check.
I will definitely come back to this Shangri-La when I get another opportunity to visit Bangkok.
