when you first arrive at in front of the building you get scared, as it looks really unfriendly. Then you enter, go on first floor and enter the hostel and you immediately feel more comfortable, it is really cosy and the staff are really really really nice. If you have a question, just ask them and they will help you (they helped us booking bus ticket to krakow).
unfortunately, I couldn't sleep well in this hostel, as it was really really to hot in the room. We decided to open the windows, but we were facing the road and it was really noisy.
