I love the silom village inn on silom road. my friends, who live in bkk for yrs, take their extra ladies there. It is 10-12 min walk to patpong and the mall on silom. it cost 1000 baht/night when I was there 8 mos ago (busy season). I take back 2 girls a day there. no charge and they are cool with good service. lots of nice restaurants to walk to in the area. it is a pretty big 1 bdr for thailand with good bathrooms. it is clean too with a safe.
its about 100 baht taxi to nana plaza and the great discos. I encourage you to hit the clubs and not just soapies and gogo bars. the girls at the discos are even more desperate and better looking. they have overhead, they paid to get in the club.
