"A very good hotel in a very good location.
GCP T21 has a very ellegant look and feel to it but still maintaining updates/ upgrades to meet modern time needs. Located in the Asok area, right behind the iconic Terminal 21 shopping centre and has acess to the upper level should you want to catch the BTS as well.
The hotel is quite modern, and has full facilities from pool, gym, bars and more. The room itself is also reasonably modern and will cover most needs (i.e., if you are staying with your family and need a washing machine/ dryer, they have rooms that can cater to this or if you want a smoking room, they have floors dedicated as well).
I got myself the Grande Suite which is around 65 sq mtrs in size, which is a one bedroom hotel suite with a separate bathroom, living room and kitchen area. The kitchen is a full kitchen, with a full sized fridge. Very good if you are on holiday with a family. I had a rather high floor and thus the view was magnificent, showcashing the south Bangkok city skyline.
Overall a very good hotel room and hotel which I expect from the GCP range. There was only some minor issues I would say the room has (but I would say is not something most will encounter) and that is the bidet feature of the Japanese toilet was not working. Also, the channel selection seems to only cover certain groups of people and English speaking isn't really one of them (not major issue as I'm not there to watch TV, just pointing out and is just my opinion)."
