I've tended to stay at the same places on most recent visitswhich is the royal president and more recently the grand president
Main reason has been the suites where you get a fair amount of room space - bedroom + living room - feels nicer than just a bedroom
Cost has been about 2000-2500 baht
Also don't have joiner fees, have decent sized safes.
Wireless internet is also a priority for me which grad president wasnt great for last time if I remember - had a wired connection which could use and seem to remember doing last time due to wireless problems at grand president.
Grand president is also on soi 11 and next door to climax night club.
Like the Royal president as not much in the way of noise but pool isnt that great.
