We stayed 10 days at Geraldine's pace to visit NYC, which was a very good decision. Getting into NY is very easy via the close (5min walk) Groove Street Path station. The place is like the pictures show and everything was clean. Easy to operate kitchen and big comfy bed (+ a big TV to watch Netflix/Amazon). The private bathroom (specially shower) was a little bit smaller than expected but that was not a problem for us (and I'm 6"2). Due to the nature of the building, you can hear footsteps from the apartment above pretty well but it's not too loud and was not an issue for us.
Communication with Geraldine was super easy and we always got a very fast answer in case we had a question.
Overall a very nice stay at her place and perfect location to check out NYC and Jersey City.
