To be honest i don't know why people have written so many good reviews for this hotel, in my opinion this is just an OK hotel. This is a 3 star hotel with most o the facilities that a 3 star hotel should have.
The room is dark with insufficient light system, probably they want to give it an ancient look :D However, the room is big enough with a balcony with the facility to dry your clothes. Bathroom is clean, though there was a problem with the tap of the basin. Eery time i turned the tap on, water kept coming out in such a way that i got wet. They did not fix it even after complaining.
The location is so bad, there is no sky train station nearby, not many bus routes around. If you want to go to city, the only choice you have is taxi which will never go by meter. For example, if you want to go to MBK shopping mall or Siam centre, if you ask the taxi to go by meter (which is actually 70 to 75 baht), they will reuse to go by meter and ask you to give them minimum 200 baht .
I had to stay in this hotel because i was attending UN training and this hotel is just 10 minutes walking distance from United Nations building. You can choose this hotel only if you have to go to UN office everyday.
Their complimentary buffet breakfast doesn't have many options, still good i would say.
They have free internet, you can use it in your room if you have a laptop, but you have to ask for username and password everyday because it expires in 24 hours after first log on.
The rooms on 2nd, 3rd and 4th floor were of 1200 baht , they call it standard room; and rooms on 5th and 6th floor were of 1600 baht, they call it superior room. However, there is no difference in these two type of rooms, some of our colleagues chosen rooms on 5th and 6th floor and regretted later. By the way, they are going to increase the room rent soon, it will double without any reason!!!
Some people have written about their thai massage, i don't think their massage is good, rather you can get a very good and cheap thai massage outside such as in Wat Po and Wat Po has a branch in Sukumbhit area also.
