Conrad Hotel Bangkok is the best.

During the Golden Week of 2025, I stayed at the Conrad Hotel in Bangkok. It's one of my favorite hotels in Bangkok. The pool is spacious and open, and the gym is large and well-equipped. Of course, there's also a sauna. Additionally, the Executive Lounge offers a refined dining experience, which is quite impressive for a Hilton-affiliated hotel. There's a shopping mall right next door, and it's connected internally! The rooms are equipped with bidets, making it a comfortable and highly recommended hotel.
