We stayed at Seng Hout for 3 nights in July 2009. It was one of the best value-for-money places we stayed in in Cambodia. Our room (Dbl room at $13) was a good size, impeccably clean, as was the bathroom.
We had free Wifi in our room, which was a pretty good speed. There were also computers with free internet in the lobby downstairs. The staff were all really friendly, although some of them didn't speak a lot of English (not a huge problem though, their basic communication skills were fine).
The only problem was that the bathroom was a wee bit smelly - always fine for a few hours after they cleaned the room, but the smell would come up the drain and be a bit distracting. If we'd asked to move, I'm sure they would have moved us as the hotel was quiet but we weren't too bothered by it. Still, that would be my only criticism.
