I had a good stay at the Generator hostel since it is close enough to the city center and offers everything you need, the staff was very nice as well. The only thing I did not enjoy was that it was not possible to open a window in the room and there was no ventilation in the bathroom. That is why it was always really humid in the room (especially after someone showered), even in the hallway.
I would not stay in the hostel again, but for my short spontaneous stay of three nights, it was okay.
