I stayed for one night at this Airbnb before my scheduled flight at Newark. The location is amazing as it's walkable to Penn Station and the train to Newark, along with Time Square and a lot of other attractions.
I was there before the check in time and was able to store my bag until check in and after I checked out the next morning. Despite having to deal with a loss of electricity the previous night, Michael was very friendly and very helpful in recommending a nearby food festival for me to explore. The check in and out process was quick and smooth.
As other reviews have note, the space is small but adequate. If you are sensitive to noise, then earplugs would be a necessity as you will hear almost everything that goes on around you. As I was only there for one night, it's was great and suitable for my needs.
