We stayed at Bob and Francois' apartment while we were undergoing a renovation in Manhattan. It's really close to the path train and is easily in the best location in Jersey City for bars and restaurants. Würstbar and The Archer were a couple of our local favorites.
There are also plenty of grocery stores within short walking distance (if you stay there, check out "Sprove", the organic supermarket at the far exit of the path train which is open from 7am-10pm every day).
The house is clean and cute, with a large closet and a spare room for your luggage. The washer/dryer is a godsend for longer stays.
Francois met us at the house when we arrived and took us through the everyday runnings like which keys were for what and how to operate the appliances. They're both lovely guys and were always quick to responded to any queries we had.
