The photos listed for Tim & Stacey's apartment are completely accurate -- it's a beautiful remodeled space! A very comfortable bed, a gorgeous full kitchen and a lovely bathroom, all very clean and quite modern. We stayed on a very hot weekend and had to get the window A/C working for quite a while before things cooled off, but then we slept well. And Stacey was very responsive when I couldn't seem to work the upper lock and kindly let us store our luggage for a few hours the day we left.
The thing is entering the building -- you really need to prepare for a tenement feel walking up the stairs -- it is pretty dire. Folks from the NYC area probably wouldn't blink, but I almost turned and ran. Thankfully it was still light and I got into the apartment upstairs and saw how nice it was!
And, yes, the Path train is walkable in perhaps 15-20 min., but in the rain and at night we wound up feeling the need to take a Lyft. Again, we are no longer as young and hip as we once were...
All told, I think this place is excellent value for money -- you would have to pay hundreds more for anything like this in Manhattan. Especially if you need an extra bedroom. It is truly a beautiful space upstairs! But there are some downsides to staying in Jersey City as well.
