Nana Plaza has some hidden short time hotels, such as:
ST hotel 1: 2nd floor (3rd to septics) - in between Cascade and Carnival.
ST hotel 2: 2nd floor again, turn right out of Hollywood Carousel and it’s past the stairwell, next door to the beauty salon, above Farang Connection and Rainbow 3.
ST hotel 3: 4th floor(!) - go to the doorway of Erotica, but go up the small staircase instead of going into the bar. Past the door into Erotica’s (closed?) second floor, keep going straight ahead and don’t look down.
ST hotel 4: Mandarin?
Mandarin bar may or may not also have short-time rooms available upstairs (Some girls say it does, others deny it completely. Upstairs has been closed recently so maybe that has something to do with it)…
Bangkok Bad Boy at Farang Speaks 2 Much
In the short time ‘hotels’ within Nana Entertainment Plaza itself they are about 300bht an hour for a very basic room. The beds are big and not that bad (in other places, such as one I used recently in Pattaya, the bed was impossibly hard). The room had a shower and towels and soap.
