Great stay in Jersey city! It's close to the Path station and Hudson river. The neighborhood is safe and very walkable with a few coffee shops nearby.
The room is spacious with everything I needed, e.g. electric kettle, utensils. The private bathroom is only a few steps away from the bedroom. Charlotte has helpful hand-written notes everywhere! She was friendly and responsive all the time and mailed me a charging cable that I left there.
The only caveat is that there was some street noise and the mattress was a bit too soft for me. I slept better after a couple of days after getting used to it. I would definitely come back if I visit again.
