I have to reply to this I never knew what a curtain hotel was,
It was my birthday so went out drinking and eating with my wife around Sukhumvit
decided to get a taxi home to the place we were staying, a friends house, taxi green/yellow she told the guy the address and off we go, the taxi driver from surin,isan some where north east, I think of them as the Geordie of Thais,
went over the pinklao bridge left turn into
the curtain motel, as they pulled the curtain behind the taxi I thought it was a robbery or I was going to be shot, anyway after so laughing my wife and the taxi driver confirmed the address, it was on the next soi, no gps 30 years ago,
ps still with the wife!
