The place is a hostel, so after booking a single room I actually got a room with bunk beds all for me, which of course didn't make any difference to me. I must have been unlucky, though, considering all the reviews here on TA that praise the cleanliness of this hostel, for the shared bathrooms and the room's floor were fairly clean, but the sheets on the bed left a lot to be desired: they were crumpled and definitely didn't smell as if freshly laundered. My fault I didn't speak up about that immediately, but I was too tired after travelling for 12 hours and didn't feel like arguing.
Apart from that, this hostel is good value for money: the price is unbeatable in Manhattan; location is excellent, on the East Side near Madison Square Park and the Flatiron Building; breakfast is good, with coffee, milk, waffles, fresh fruit, cereals (though, maybe because I would have breakfast at 7, I never saw things other reviewers mentioned, like pancakes, eggs and pretzels), and my room was even provided with an air-conditioner (small, a bit noisy and rudimentary yet effective). All in all, I would recommend this place to non-fussy travellers (provided you check your room and speak up if something should be wrong :-).
