Very clean with easy access to the train! The host is very communicative and easy to work with. The apartment is modern and simple with nice views (including a lovely rooftop space with a view of the New York skyline).
The train will take you to NYC and is about a half mile walk. It takes you right to Penn station where you can connect with several subway trains. To us, that makes staying here a very economical way to visit the city.
Newark is definitely a bustling (and noisy) place and our neighbors were very active on the weekends. During the week, it was significantly quieter. As it's likely to be noisy almost anywhere, it's just something to be prepared for. Bring ear plugs if you're sensitive to loud noises at night.
Access to the building is well-explained and the parking spot is such a benefit! Given the proximity of the train station, we left our car in the lot most of our stay and took alternate transportation.
There is a lovely Whole Foods, a delicious pizza shop, Starbucks, and plenty of parks and outdoor spaces nearby. They are all about a mile away.
All in all, a very convenient and economical place to stay.
