Well, getting bitten by bedbugs all over my back, overshadows the review. Awful.
That said, the place is easy to find, seemed popular, and is close to the ultra modern Terminal 21 shopping centre, seedy Soi Cowboy and the seedy area around Nana. Also May's Veggie Home is nearby - excellent Thai restaurant with AC; heaven for veggies. There are two skytrain stops close by, so transport is easy.
I stayed in a room with 2 bunks (4 beds) and small ensuite bathroom. There was one other guest but she didn't even come back during the night (I got back at 4am myself), and I met her downstairs as I was leaving!
Bedbugs aside (and that's a massive aside), this place is ok for backpackers. It was fairly quiet, too.
