Have stayed in this Hostel a few times for trips to see local team St Pauli. It's slap bang in the centre of the Reeperbahn, so stag and hen parties are rife. You can choose rooms with en suite and television, which is all I need as far as extra facilities go, but it is like a sweatbox in the summer due to lack of ventilation/air con.
It is suitable for a certain type of traveller due to it's location. Have stayed in worse and it serves it's purpose.
