This apartment is very close to Newark Penn station and was very convenient to get around. The place was very clean and we appreciated our stay there!
There is a restaurant above the Airbnb which can get a bit noisy at times, but it didn't bother us at all. The jets in the tub did not work, but we could still use it as a regular bath tub. The air conditioning didn't work either: it was a bit warm the first night but it was better the second night because the temperature dropped significantly outside. Ruy did leave a couple of heaters in the apartment, but since it was fairly warm, we didn't end up using it. Air conditioning would have been good if it was warmer but we were able to manage.
Overall i think it was a convenient and affordable place to stay when visiting the NYC area. I would definitely recommend it.
