The Hostel is really nice and artsy, everything painted or handmade, we liked it a lot! The location in the city is perfect, 10 minutes from the central Station by foot and right in the center - really nice bars right in front of the hostel. In addition Pia and Juri are really sympathic.
The only thing that we could critique, is that we thought we would stay in an own room which we would be able to lock. Only when we arrived, we realised that we'd sleep in a loft bed situated in a room with two doorframes leading right to the other rooms in the flat. Maybe we didn't read the description careful enough, but we were surprised by that...
