Holy Buddha ... NO
Grace was the first hotel I ever stayed in TH, (1999) and the worst ever, worldwide. Thankfully only one night, and off to Phuket the next day. Patpong, again, one of the worst, if not, areas of Krung Thep, if not TH. Scam central.
When I did finally hear about Thermae ... took the advice and avoided. All 3 visited by lowest scrapings of the barrel.
