The XBerger Hostel is located in the district of Kreuzberg, not far from Oberbaum bridge and the East Side Gallery. You can get there by Line U1 U-Bahn station exiting at Schlesisches Tor, or by the bus 265. There is a 24 hour front desk, but you can't check in before half past four in the afternoon. They offer luggage storage if you want to visit the city in the meantime. Next door, there is an interesting control tower from the former border between East and West Berlin. Prices start at 11 euros per person per night in low season for a 16 person dorm, then up to 16 euros for a 3 person shared-room and 18 euros each for a double room.
