We (my wife, daughter & me) stayed in Patumwan guest house for about a total of 10 days in Jan-Feb 2011. We found the hotel clean, comfortable and spacious. Despite being close to major commercial centre (Siam, MBK) the hotel is secluded and quiet. We could even leave our suitcase in their store when we went away touring to some other neighbouring countries.
Improvements needed in WIFI connectivity in rooms. Restaurant should be improved. I am glad to learn that breakfast package has been started. One most important thing would be to provide tea/coffee making facilities in room. It will make a huge difference.
We would definitely stay in Patumwan House again, soon.More
