Stayed here for 3 nights in the past week.
First, the location is simply great. It is just a very short walk to the Asoke BTS station (next to the excellent new Terminal 21 shopping centre) which can travel to most places in central Bangkok. Helps to beat the nightmarish traffic in the city. It is also tucked away in the side, away from the main street, thus being somewhat of a quiet oasis in the city.
Second, the service is very good. Check-in was prompt. Their free airport transfer package was very good. Breakfast was healthy and decent. Electric plug converter could be loaned at the reception. Wifi was excellent. Free copies of THE NATION newspaper was available daily at the lobby. The reception was also helpful in helping us to book Thai massage at the Healthland Asoke upon request.
Third, the rooms were very clean and well made daily. The shower was very good. Free bottles of water were replenished daily. Bed and pillows were very comfortable. There were even bath robes in the rooms and slippers.
