We have spent a week at Richard's house in Jersey City. The place was really clean, and even if we don't appreciate it in the pictures, quite spacious.
All you would need is provided (sheets, towels, soap etc...), and there was even a coffee machine with available coffee/sugar; and a big TV with Netflix access included.
There are a lot of options for grocery shopping, some fast food close to the house (Subway, Dunkin Donuts...) and the Miss America diner just at the corner which is really worth it, especially for breakfast.
The place is located in Jersey City, meaning that you would need around 45min-1h to go to dowtown Manhattan. The light rail is just a few blocks away, and then there is the Path train or a bus to get to the center. It's a convenient option to have a peaceful rest after a busy day in NY, as it's really silent during the night.
Communication with Richard was very easy-going, he was always quick to answer any doubts we may have and gave us some recommendations of things to see outside of Manhanttan. On our last day, our plane was quite late and he also gave us the option to store our luggage after we check out so we won't have to carry it around all day.
We would definitely recommend staying at Richard's house, and won't hesitate to come back if we have the opportunity to come to NY again. Thanks again for everything!
