Jomtien is a nice place to live ,it has a bit of everything for everyone with a great night market (it had before Covid).
It just depends on your age group ? 20 to 45 yrs it will appear quite boring with very little music & night life, 45 to 60 yrs it appears to be a nice place to live without all the headbanging music, 60 to my age 76 yrs it's absolutely heaven, with quiet nights at home etc.
It's also cheap to live in Jomtien Beach.
