Had a good stay at Central Backpackers in Vang Vieng. Great space to meet other backpackers and the dorms were clean, comfy enough and cheap. Good location and close to tubing place and most of the bars. They really need to work out their website though, you can only call to make a booking and the email address on the site sends you a bounce back. I got a bit stuck here waiting for my Vietnam visa and by the end was very ready to leave. Don't recommend staying long in Vang Vieng but if you're passing through to do the tubing central backpackers is a good hostel. The staff are pretty friendly and there's one guy there on staff who's a bit weird but in the end he kinda grew on me.
