Just back from a wonderful vacation in Bangkok. We had a great stay in Prom Ratchada hotel. This hotel is well located near to the MRT Thailand Cultural Centre, big malls such as Esplanade, Big C and Robinson. There are plenty of restaurants nearby, with mostly Japanese restaurants. It's worth to try the buffet at Sukishi restaurant located at 2nd floor in Big C. A wide variety of food with only about THB 315 per pax. We booked the standard room through Agoda.com, and got a free upgrade to superior room. The room which we stayed was very clean and spacious, with free Wi-Fi and all the basic amenities.
I must comment that the service at this hotel was superb. Most of the staff in this hotel could speak English and were very polite, helpful and friendly. Keep it up!
The only downside was that the hotel was not using keycard system for each room. So, someone has to lock the door manually and 'slam' it in order to close the door when out. It was kind of disturbance to us especially late at night.
All in all, this is a lovely, fantastic hotel with reasonable price. I would definitely come back again for my next visit to Bangkok.
