We picked Sima Thani because we thougth it was the best hotel in Korat.
After staying here we must say, it is good but not great.
After checkin we found on arrival at our roomn that it was a Smoking Room - having 5 months earlier at time of booking requested a Non Smoking room!
My wife ( thai ) contacted reception and asked for a non smoking room, to which they replied 'are none' we try to find you less smelly room!
Well a quick trip to the manger by myself found us upgraded to a better room - non smoking of course.
The continental evening buffet is really good - must do and enjoy.
Would I stay here again - probably not.
