sukhumvit soi 4, if i am not mistaken name is Rajah hotel. Before Annie's Massage. There is some Thai guy at ground floor and he will show you to go up lift. Mostly Russian/ USSR gals with some Asians.
Another place is soi 3, opposite Grace Hotel there is some hotel offering such exotic foreign gals.
Disco in Grace Hotel soi3 also has some Russian gals but likely more Arab and these days African gals also
