I will let the guys more in the know to answer your main points. However we are in the travel business and survey camps and hotels then publish full consultancy reports (confidential). We highly recommend Backpackers indeed we hope to stay there for a couple of weeks next month whilst we get our house ready (if they would answer our e-mails!) However the one weakness is their dorms.
There is also a block of four rooms available with beds. This block does not look appealing. They are not en-suite.
We did not have a chance to look inside (occupied) but judging by the outside they are very basic. You would be much better off in a tent. Great bar set right on the river, fantastic atmosphere. One down side is that it is a long walk to the road to hitch a lift if you don't have transport.
