As unpretentious and uncomplicated as accommodation ever gets, the Xberger covers all the important bases - no curfew, common kitchen with free tea and coffee, free internet, women-only rooms, luggage storage, pool room. Everything else - as a visiting schoolteacher might declare to his class - is a privilege, not a right. The smallest rooms have four beds in them, and the largest 16, so you're likely to have the company of savvy students looking for the essence of Kreuzberg.
Kreuzberg's Wrangelkiez nearby, which has flowered in the last decade, is this hostel's biggest asset, and many of the residents here are new Berliners looking for a flat. Perhaps because of this area's tightening property market, which means that the bed prices here almost undercut the average local rent, there is a one-month limit on the length of your stay.
