Pro: The staff was nice and helpful, one of them were even distributing his own sweets around the reception :) They warned me about the strikes. I liked the free welcome drink and the stamp collecting card, the breakfast and rooftop. The kitchen was clean and well organized too. The little shelf for the phone charging next to the socket and the small lamp above the bad was just excellent.
Con: I didn't like that I had to leave my id card at the reception each time when I went out. It's a nice and customer friendly hostel which satisfy almost every needs of a backpacker, but I was missing something from the atmosphere. It's just really too big to get to know other people easly.
