I was in a room with 2 pods, so I only had to share the room with one other person at a time, and the cohabitation always went well. The room is tiny, but there is a locker to store valuable items in (you have to bring your own lock). Every member of the staff I met was always friendly and helpful. My main complaint would be the noise: as others before me have already mentioned, the ventilation in the pods is very loud. Also, whenever the central heating was turned on, the pipes would make a huge banging sound on and off for hours in the middle of the night.
The showers were clean and had hot water, but I found it a bit odd to have mirrors facing the shower doors, which were glazed but still too see-through in my opinion.
It would also be nice to add hooks in the toilets and near the sinks.
All in all, I felt safe, the hostel is in a nice neighborhood and right next to Central Park, the subway is a few minutes away. But make sure to bring ear plugs with you!
