We chose this place because of it's central location, cheap rooms, and solid reviews. The building itself was painted over in pretty unique artwork and graffiti which could be seen by the S-Bahn station right across the street. We had essentially no issues with the rooms and lounge spaces for the single night we stayed. The luggage storage even saved us on the morning we checked out, so that we could explore more of the city without having to commute with our luggages.
Also, to echo what other reviewers are saying - the 50 EUR deposit for the room key and the meek wifi are just a bit concerning. However, this hostel should be recommended for budget travelers wanting to stay in the city in a great location for great prices.
