It is a good hostel if you stay for just one night, but I wouldn't recommend it for longer. There is only one bathroom and shower for many rooms, there is no soap and they don't provide the towels (many hostels do). I also missed some good lockers. Otherwise the staff is really nice, the atmosphere amazing and it even looks cool, because this house used to be a cinema and the rooms are actually projection & staff chambers.
It is an OK hostel, but it doesn't have any kitchen or anything that would a regular backpacker/traveler need. Additionally I disliked the fact that you have to put your key-card into a special slot to make the lights work. Also - a towel would be nice. This hostel tries too much to look like a hotel. But the breakfast is really nice :)
It is one of the best hostels I've ever been to. Very small, but with a good atmosphere and extra friendly staff. :)
