When we arrived in Jersey City, we were welcomed by Freddie, the housekeeper of the hostel, who was very kind and showed us around the house. The room (number 2) was cozy and very close to the bathroom. Only the walls seemed to be very thin so that it used to be a bit noisy at night and also the room couldn't be fully darkened because of the street lights in front of the windows.
The hostel has a great location, it's only a 3 minute walk to the PATH Station Journal Square that brings you to New York City in about 20 minutes. It is a very good place if you want to visit NYC.
