Our stay in Jersey City was fine.
Just be aware that if you want to go to NY you have to walk 10 minutes to the tramway, then take the Path to arrive in NY. That’s ok.
We took a coffee every morning to « The Grind Shop », on the way to the tramway, very cheerful people.
Be also aware that the living room is shared with other people (other tourists?) we don’t even know because they were just passing by, it was kinda weird.
