Sorry (the english say my home is my castle, but as one may be looking for signs).
As above I am not a Pty expert at all, having been not here since >20 yrs, but yesterday I walked around central, to check out and saw beside tuk.com Somjit, then Relax@me, then Helios (noone sitting outside). I missed this Royal HOuse and with much searching found it should be in Day-NIght soi #20/213, may check again today-or not. And then saw the sad remains of what once, long ago, was Sunee, for whcih I have good memories.
In soy Boyztown is Paradise, with late afternoon just 1 rather effeminate guy-not my choice. Its also 100 bt more expensive as all others.
Some said Paradise is related to the 2 in BKK (along Silom, soi 2 and 6) and also is in Jomtien-but that shop is closed and looks abandoned. I did not ask the guys opposite (Sunee bar?) if this is definite or whatever.
Saw another rather specific recomm for Jomtien Health along main rd just north of Supertown-it has mixed staff and many diplomaĆ that should attest its qualified staff. I would rather see (and I guess perhaps even latin too) plak-an or diploma on what extra is available. The smiles etc of the ladies staff when one chooses a male masseur (moh nouat) are for me already a deterrent to go in then.
