Anyone know any cheap accommodation with private bath near Rankamhaeng area of Bangkok or the upper Phetchburi Road area near Rankamhaeng?

I used to live near the uni and am quite sure there are no guest houses. There are a few hotels on Ramkamhaeng though, walking distance to the uni. The best bet is the Chaleena Princess on Soi 65, (opposite the more expensive Chaleena hotel) about 480 Baht a night including breakfast. If you stay here you can use the Chaleena's pool. They speak very little English here. There's another I think on Soi 22 or 20 that looks a little pricier.

Thanks.
