Teo is a great host! And very quick to respond to messages.
We stayed in the tiny home for a week and it suited our trip perfectly. It was clean and It's about a 20 minute walk to the Path Train or a $5 Lyft ride (the Path takes you to WTC station, or more uptown to 33rd) we usually walked in the morning and took a Lyft at night when we were tired. From this spot it is very easy to get to NYC but is a cheaper alternative than staying in the City. It is also a short Uber or Lyft ride from the Newark Airport.
Jersey City doesn't offer a great deal for walking around, but this is a great place to stay if you are planning on spending your time in NYC.
