Walk into the bathroom and there's a waterfall eddying down a Perspex wall into the urinal. Upstairs, in the all-girls Sanctuary level, there are Egyptian cotton sheets on the bunks, full-length mirrors, en-suite bathrooms, hairdryers and Aveda products for an extra 80p. Nowhere are there junk-shop sofas that look as if they should carry government health warnings. Everywhere you look it's clean, classy and, well, civilised. It's backpacking. But not as we know it.
