Try Omyim Lodge

I stayed there a few times before. Its next to the skytrain station and 5 mins walk to Silom soi 2 and 4.
They have double glazed windows, so no noise or try one of the two windowless rooms(big rooms)
Prices are from 800 bht to 1500 bht includes breakfast (big and tasty) and taxes. No joiner fee and friendly staff. I only ever stay there if I can get in. You need to book as soon as you can.
