It was a such a great experience when I stayed at St Regis Bangkok for my birthday vacation. The butler's ready to serve you for 24 hrs whether to bring a hot tea at night or press 2 shirts per person per day. I addition, the butler gave me such a cute birthday surprise when I came back to hotel. The location is also very comfy because it's connected with BTS Ratchadamri on the 2nd fl. Check in- Check out process was also pretty smooth. Something St Regis Bangkok might probably improve is on the breakfast menu. Because they always serve the similar menu everyday so it's kinda boring. But overall It was a great experience and I can't wait to stay there again when traveling to Bangkok in luxury.
