I lived there in 2018, and traffic insane, but it always was around the moat, even in 1974.
C M problems are IMO because there is no planning by council, and council doesn't keep place clean, or carry out maintenance. They didn't even do anything for New Year like Pattaya did.
Worst nightlife of a tourist place in LOS.
Public transport is a bad joke with rip off red songtheaws.
I stayed there because didn't want night life and it was cheaper than Pattaya.
