Well, I hate the place.
Full of cheap decrepit condos that were sold as luxury developments less that 10 years ago. I know, I was here. The malls are just a bit bigger than community malls. The traffic makes Bangkok pollution even worse. W district is ok for younger people. Much better places around MBK (samyan) Silom, Sathorn..... but of course it costs more to live there. I used to live on Ramkhamheang near Bangkapi mall. Much better choices of everything than On Nut will ever offer including Western food choices.
