Liked: At a time of year when the cost of staying at a hotel in Manhattan was through the roof, the hostel offered a helpful alternative. The cost, while still expensive, was reasonable, but the facility was well-maintained, the bed comfortable, and the shared bathrooms were clean.
Disliked: There wasn't anything I didn't like. The place is close to Penn Station, easily reached within a few minutes' walk. I would stay here again if hotels continue to be unaffordable.

Bad

Liked: NOTHING
Disliked: It wad a dirty filthy hole. The owners weren't very helpful. Only 1 towel to share between 2 persons as apparently the laundry wasn't done from the day before. Got a coat stolen from the kitchen area the owner thought this was very funny.

Liked: Nothing.
Disliked: I arrived on site to the property but no one responded to the doorbell or let me in. No one answered the phone or responded to messaging over booking.com. I had to book another hotel somewhere else.

Liked: Great location, clean rooms and bathrooms. Once we were there, great staff service.
Disliked: We sent a request (by email, phone call, contact on booking's page) to leave our luggage before check-in, we only got automatized answers. Didn't help until we were checked-in.

Excelent!

Liked: The location is great, the rooms were clean.
