Bro,
About S$45/night. can choose to have twin room too if u prefer for the same price. Come's with buffet breakfast which is not too bad. Else there's 2 eateries just outside the hotel and also a 24hr convenience store. If you like a regular massage there's 2 too.
Nana Plaza is not too far, I didn't go cuz too many Chow Ang Moh there. Rathchadapisek is but a short ride in a taxi, depending on the time of day. I went to Cupidy and Nataree. Word of advise, don;t spring for the sideliners, good to see only, play delay tactic in the room.
I think the senior Cheongsters are in another thread 'massage parlour girls" or something. lotsa new posts there, maybe can ask them for further advise.
SQ now have one going for $168, think it's for a certain flight only. Can try.
Manhatten hotel Bangkok can book thru online agencies which have better rates, goto

Cheers!!
