My experience: I came to the hostel quiet late at 1:30AM to spend my only night there. I was told that they are full and they cannot accomodate me because they were waiting for me till 1AM to show up or call that I'll be late . Good to say I agree I should let them know it was my fault. So I asked if I can stay in guestroom at least (night in NY's streets it's not that safety) when they said okey you can sit but pay same as for the room. So I left but they charged my card anyway later on. Thanks
After our arrival to the hostel we found out that what we booked is actually not available. Two options were offered to us then. First sleeping in room with some stranger or sleeping in room without heating. We chose nonheating one distants 15 minutes by walk from hostel office. For 4€ it's kind of good service but for your review I had to pick up "very poor smile" many times.
Noisy mattrasses, if you want to move you can wake up everybody in the room.
