There are quite a lot of guest friendly hotel list in BKK available. http://www.guestfriendlyhotel.com/guest-friendly-hotel-bangkok/
Highly recommended to stay near Nana Plaza/ BTS area that is walking distance to most of the bars, BJ salon etc and most hotel around here is guest friendly. There are quite a few BJ bar in Bangkok. Can try Kasalong, Som's Haven, Lolitha;s, Star of Light etc mentioned in others threads in this forum.
